The SIS is intended for the planetary science scientific community who will analyze the data. 3 Instrument Overview The OSIRIS instrument was provided by the OSIRIS consortium led by the principal investigator Dr. Horst Uwe Keller at the Max Planck Institut für Sonnensystemforschung. The OSIRIS consortium has the following members: MPS Overall responsibility and project management, system engineering, interfaces, Focal Plane Assemblies, CCDs and Readout Boards, HK Boards, integration &qualification of E-Boxes, harnesses, system integration, high level software, NAC & WAC system calibration, QA, mission operations LAM NAC telescope, camera integration and qualification WAC optical bench, camera UPD Integration and qualification, shutter mechanisms and shutter electronics, Front Door Mechanisms (mechanisms for NAC and WAC) IAA Mechanism Controller Board INTA Filter Wheel Mechanisms, E-Box Power Converter Module, NAC & WAC CRB Power Converter Modules RSSD Data Processing Unit IDA Mass memory, low level software and data compression DASP NAC & WAC Filters UPM Thermal and structural analysis, NAC MLI, WAC FPA MLI The OSIRIS camera system consists of a narrow angle camera (NAC) and a wide angle camera (WAC). 3.1 The narrow angle camera (NAC) The NAC uses an off axis three mirror optical design. The off axis design was selected in order to minimize the strayligh reaching the CCD (The NAC has a proven stray light attenuation of better than 1.0e-9). The optical beam is reflected of the three mirrors (M1, M2 and M3) before passing through a double filter wheel, a mechanical shutter mechanism and an anti radiation plate (ARP) before reaching the CCD.

So the typical WAC observation uses either the filter combination (empty + filter) or (filter + empty) The WAC is equipped with the following optical filters: --------------------------------------------------------------------------------------------------------------------- | Name | Wavelength | Bandwidth | Peak | Objective | Thickness | Wheel | Position | Encoder | | | [nm] | [nm] | [%] | | centre [mm] | | | [DN] | --------------------------------------------------------------------------------------------------------------------- | Empty Empty position 1 1 14 | | to allow | | the use of | | filter wheel 2 | | Empty Empty position 2 1 14 | | to allow | | the use of | | filter wheel 1 | | UV245 246.2 14.1 31.8 Continuum 4.51 1 3 4 | | surface spectral | | reflectance | | CS 259.0 5.6 29.8 CS gas emission 4.60 1 4 7 | | UV295 295.9 10.9 30.4 Continuum for OH 4.75 1 5 2 | | OH-WAC 309.7 4.1 26.0 OH emission from 4.82 1 6 1 | | the vicinity of | | the nucleus | | UV325 325.8 10.7 31.6 Continuum for OH 4.85 1 7 8 | | surface spectral | | reflectance | | NH 335.9 4.1 23.6 NH gas emission 4.86 1 8 11 | | UV375 375.6 9.8 57.3 Continuum for CN 4.60 2 3 8 | | surface spectral | | reflectance | | CN 388.4 5.2 37.4 CN gas emission 4.61 2 4 1 | | Green 537.2 63.2 76.8 Dust continuum 4.71 1 2 13 | | NH2 572.1 11.5 60.9 NH2 gas emission 4.74 2 5 2 | | Na 590.7 4.7 59.0 Sodium gas 4.75 2 6 7 | | emission | | VIS610 612.6 9.8 83.4 Continuum for OI 4.65 2 8 13 | | surface spectral | | reflectance | | OI 631.6 4.0 52.4 O (1D) gas 4.66 2 7 4 | | emission | | for dissociation | | of H2O | | R 629.8 156.8 95.7 Broadband filter 4.67 2 2 11 | | for nucleus and | | asteroid | | detection | | (NAC redundancy) | --------------------------------------------------------------------------------------------------------------------- Table 4 The WAC Optical Filters 3.3 The Mechanical Shutter Mechanism Both the NAC and the WAC cameras are equipped with a mechanical shutter mechanism for controlling the exposure time. The shutter mechanism uses two blades to control the exposure. The first blade covers the CCD at the start of the exposure. when the exposure is started the first blade is accelerated to 1.3 m/s before the edge of the blade reaches the edge of the CCD. the blade edge then passes over the CCD at constant velocity before being decelerated to standstill after passing the far edge of the CCD. The end of the exposure is controlled by performing the same motion with a second blade that initially is outside the CCD surface. The second blade motion starts after the exposure time has passed from the start of the first blade motion. The full blade travel lasts 53ms. For exposure times shorter than 53 ms the blade motion of the two blades overlaps. In this case the exposure is controlled by a moving slit (same principle as a SLR camera). During the blade motions the position is measured using a position encoder mounted on the drive shaft of the shutter motors. The minimum allowed exposure time is 10 ms and accuracy of the exposure is better than 5s Figure 4 The OSIRIS mechanical shutter mechanism 3.4 The OSIRIS CCD The OSIRIS camera system uses 2048x2048 pixel backside illuminated CCD's. The CCD's are equipped with anti reflection coatings optimized for the UV spectral range. The CCD's are equipped with shielded anti-blooming control. The CCD's are UV sensitive down to 240nm (50% QE) and IR sensitive up to 1000nm (6% QE). The system gain is set to ~3e- in normal operational mode. The readout electronics is using a dual 14 bit ADC configuration giving an effective 16 bit system. The CCD's uses two readout channels (channel A and B) which can be used in parallel for fast readout. Figure 5 The OSIRIS CCD mounted in the focal plane assembly. The CCD's can be read out using hardware windowing and hardware binning (1x1, 2x2, 4x4 and 8x8). The fastest readout of a 1x1 binned fullframe image is 3.4s. By using windowing and binning modes this time can be reduced to less than 1s.

The GSEOS system saves the image data as OSIRIS level 0 image files (TMI or PDS format depending on flight software version). The OSIRIS level 0 images are then processed by a software application called tmi2pds used to calibrate the header information and to append various meta data like spacecraft position and orientation. The output is stored as OSIRIS level 1 (CODMAC level 2) PDS compliant image files (EDR’s). The EDR’s are then processed by an IDL coded image processing pipeline used to generate OSIRIS level 2 (CODMAC level 3) files (RDR’s). The full data flow is illustrated in Figure 7 and the processing levels are defined in Table 6. Figure 7 The OSIRIS data and processing flow (Please note that the data level referred to in the diagram is OSIRIS data levels = CODMAC data level -1. OSIRIS CODMAC Description Data levels Levels Packet 1 Telemetry data stream as Data received at the ground station, with science and engineering data embedded. 0 PDS or TMI formatted data files.

Table 6 OSIRIS and CODMAC data levels 5 Data Storage The OSIRIS images are stored as binary files with embedded PDS label. The file structure is as follows: Figure 8 Layout of an OSIRIS data file a. The image header is an embedded PDS label with associated ancillary information. The header contains object and pointer references to all other embedded objects. b. The history object is an additional PDS label containing a PDS HISTORY object. The history object contains the processing information of all the processing software used in the telemetry pipeline. c. The Image data contains the actual CCD image data from the exposure. The image data can be addressed using the primary IMAGE object. d. The amplifier A pre pixel image data contains the image data from the pre pixel readout phase of the amplifier A chain of the CCD readout. The pre pixels are 48 elements in the serial register coupled to ground instead of the physical CCD. These pre pixels can be used to estimate the CCD bias level and readout noise level. The image data is mapped to the PA_IMAGE object. The image object only exists if the pre pixel data was transmitted to ground. e. The amplifier B pre pixel image data contains the image data from the pre pixel readout phase of the amplifier B chain of the CCD readout. The pre pixels are 48 elements in the serial register coupled to ground instead of the physical CCD. These pre pixels can be used to estimate the CCD bias level and readout noise level. The image data is mapped to the PB_IMAGE object. The image object only exists if the pre pixel data was transmitted to ground. f. The overclocking lines image contains image data acquired by continuing clocking out the CCD after all the physical pixels have been read. Reading out the CCD in this manner allows a measurement of the charge transfer efficiency along the column clocking direction. The over clocking lines data is mapped to the OL_IMAGE object. The image object only exists if over clocked line data was acquired during the image acquisition. g. The Blade 1 shutter pulse object contains the raw timer data from the shutter mechanism motion encoder of the first shutter blade. This pulse data can be used to determine the position vs. time of the shutter blade during the exposure. His data can be used to improve the knowledge of the precise exposure time for each pixel in the image. The blade 1 shutter pulse data is stored in the BLADE1_PULSE_ARRAY array object. The object only exists if the shutter mechanism was used during the exposure and if the pulse data was down linked to ground. h. The Blade 2 shutter pulse object contains the raw timer data from the shutter mechanism motion encoder of the second shutter blade. This pulse data can be used to determine the position vs. time of the shutter blade during the exposure. His data can be used to improve the knowledge of the precise exposure time for each pixel in the image. The blade 1 shutter pulse data is stored in the BLADE2_PULSE_ARRAY array object. The object only exists if the shutter mechanism was used during the exposure and if the pulse data was down linked to ground. i. The error estimate image object is an image object with the same dimension as the primary image object. The image object contains the estimated standard deviation in % for each pixel based on the Poisson statistics of the exposure. The error estimate image is mapped to the SIGMA_MAP_IMAGE object. The object only exists in level 3 and higher data records. j. The per pixels quality map image is a byte image with the same dimensions as the primary image object. The quality image contains a bit field giving a data quality estimate for each pixel in the image. General rule is the lower the value the better. 0 is quality data 255 is very bad quality data. Please note that the quality map only contains an estimate based on the CCD characteristics and the processing chain the image has passed through. A complete quality estimate should include a combination of the quality map and the sigma map. The per pixel quality map image is mapped to the QUALITY_MAP_IMAGE object. The object only exists in level 3 and higher data records. The image data is stored using a PDS IMAGE object. The two Blade 1&2 shutter pulse array objects are optional and will only be generated if the relevant data has been transferred from the spacecraft. Pixel with value 0 is used to indicate lost data (lost packets). 4.2.1 PDS Label The OSIRIS EDRs and RDRs have an attached PDS label. A PDS label is object-oriented and describes the objects in the data file. The PDS label contains keywords for product identification. The label also contains descriptive information needed to interpret or process the data in the file. PDS labels are written in Object Description Language (ODL) (see PDS v3.6 specification). PDS label statements have the form of "keyword = value". Each label statement is terminated with a carriage return character (ASCII 13) and a line feed character (ASCII 10) sequence to allow the label to be read by many operating systems. Pointer statements with the following format are used to indicate the location of data objects in the file: ^object = location where the carat character (^, also called a pointer) is followed by the name of the specific data object. The location is the 1-based starting record number for the data object within the file. 4.2.1.1 PDS Image Object An IMAGE object is a two-dimensional array of values, all of the same type, each of which is referred to as a sample. IMAGE objects are normally processed with special display tools to produce a visual representation of the samples by assigning brightness levels or display colors to the values. An IMAGE consists of a series of lines, each containing the same number of samples. The required IMAGE keywords define the parameters for simple IMAGE objects: · LINES is the number of lines in the image. · LINE_SAMPLES is the number of samples in each line. · SAMPLE_BITS is the number of bits in each individual sample. · SAMPLE_TYPE defines the sample data type. 5.1 Onboard image processing and compression The OSIRIS flight software has to capability to compress the image data before transmission to ground using a number of compression algorithms and filtering schemes. OSIRIS implements a data segmentation scheme to decrease sensitivity to data loss during transmission. Each image is separated into segments with a maximum size of 512x512 pixels. Each of these blocks are processed and compressed individually. Figure 9 Example of the segmentation scheme used for an OSIRIS full frame image (2048x2048) (16 segments) All information about compression and post processing is found in the SR_COMPRESSION group in the OSIRIS image headers. Each member of this group is a vector containing an entry for each image segment used to generate the final image. The segmentation boundaries can be found using the SEGMENT_[X,Y,W,H] members. The encoding algorithm can be found in the ENCODING member. The following encoding algorithms are supported: RAW - No Compression SPIHT_D24 - SPIHT based compression used by the OSIRIS flight software prior to release 2.0 SPIHT_LIFT - SPIHT compression with LIFT filtering SPIHT_TAP - SPIHT compression with TAP filtering SQRT_16to8 - Square rooting followed by 16 to 8 bit reduction PACK9BIT - The image data has been compressed by chopping the data range at 9 bits (meaning discarding the upper 7 bits) The effective compression ratio achieved by the encoder is stored in the COMPRESSION_RATIO member. If the encoding step was performed without information loss then the LOSSLESS_FLAG member is TRUE else FALSE. Please note that LOSSLESS_FLAG only refers to the encoding step. LOSSLESS_FLAG can be TRUE even is a lossy filtering step has been performed. OSIRIS can also perform a pixel averaging step. The pixel averaging box size can be found in the PIXEL_AVERAGING_WIDTH and PIXEL_AVERAGING_HEIGHT members. To increase the quality of the SPIHT compressor OSIRIS also implements a number of pre processing filtering steps. The following filtering are possible: 1. A Gauss 5x5 convolution smooth filter 2. A Sqrt filtering step performing the transformation I_Out = sqrt(I * gain) The type of gauss smooth filter used can be found in SMOOTH_FILTER_ID with the values: 'NONE': No filtering 'CONVOL_KERNEL_1': 0.5 FWHM gauss filter 'CONVOL_KERNEL_2': 0.8 FWHM gauss filter 'CONVOL_KERNEL_3': 1.0 FWHM gauss filter If the sqrt filter has been used the SQRT_FILTER_FLAG is set to TRUE and that gain used is written in SQRT_FILTER_GAIN. 6 File Naming Convention 6.1 The OSIRIS archive filename convention The OSIRIS image files as archived in the project internal archive (please note NOT the PDS archive) use the following filename convention: CCC_YYYY-MM- DDTHH.MM.SS.UUUZ_FFLI_NNNNNNNNNN_FAB.IMG Field Description CCC eitherNAC (narrow angle camera) or WAC (wide angle camera) YYYY is the year of acquisition MM is the month of acquisition DD is the day of acquisition T is the letter T (stands for “Time”) HH is the hour of acquisition MM is the minute of acquisition SS is the second of acquisition UUU is the milli-second of acquisition FF is the image file type: the following filetypes are possible: ID Image Data (Normal images) TH Thumbnail version of the image (Highly compression version transmitted immidiately) PA Amplifier A pre pixels (calibration data) PB Amplifier B pre pixels (calibration data) OL Overclocked lines (calibration data) L is the OSIRIS processing level of the image I is the instance id if the image (multiple transmissions of an image will be reflected in this number incrementing) NNNNNNNNNN Ten digit user defined image ID number (Specified by the user when writing the command timeline) F is the letter F (stands for “Filter”) A is the position index of the filter wheel #1 B is the position index of the filter wheel #2 .IMG File extension Table 7 OSIRIS PDS data file filename elements Example: NAC_2003-10-16T13.50.05.012Z_ID21_0000000001_F82.img Is a NAC image acquired at 2003-10-16T13:50:05.012 UTC The file contains CCD image data (image type ID) with raw image data (level 1) and the image represents the 2nd transmission of the image data. The image was acquired using the filter combination (8,2). The image ID is 1. The time is the start time of the exposure. Note! The filename contains an approximate time of acquisition. This time value is only used to uniquely identify the image and should not be used for any calculation needing high precision. The time value in the filename has not been corrected for onboard clock drift and leap seconds.

The best possible knowledge about the time of acquisition can be found in the header label START_TIME 7 Coordinate Systems There are a number of coordinate system relevant to the interpretation of OSIRIS data. The se coordinate system can be separated into two groups: a. pixel coordinate systems referring directly to the CCD and b. inertial coordinate systems referring to the spacecraft and viewing geometry. 7.1 CCD coordinate frames The following four CCD frames are defined for the OSIRIS NAC CCD: 7.1.1 NAC_AMPLIFIER_A_ELECTRICAL Pixel (0,0) is the first physical CCD pixel that reaches the ADC when using the A amplifier electrical chain. The X-axis corresponds to the CCD horizontal direction and the Y-axis corresponds to the CCD vertical direction (positive away from the serial register) 7.1.2 NAC_AMPLIFIER_B_ELECTRICAL Pixel (0,0) is the first physical CCD pixel that reaches the ADC when using the B amplifier electrical chain. The X-axis corresponds to the CCD horizontal direction and the Y-axis corresponds to the CCD vertical direction (positive away from the serial register) 7.1.3 NAC_AMPLIFIER_BOTH_ELECTRICAL Pixel (0,0) is the first physical CCD pixel that reaches the ADC when using the both amplifier electrical chains in parralel. The X-axis corresponds to the CCD horizontal direction and the Y-axis corresponds to the CCD vertical direction (positive away from the serial register) The NAC_AMPLIFIER_BOTH_ELECTRICAL frame is identical to the NAC_AMPLIFIER_A_ELECTRICAL frame. 7.1.4 NAC_CCD_REFERENCE The NAC_CCD_REFERENCE frame is the coordinate frame relevant to all CODMAC 2 to 3 PDS image files. The NAC_CCD_REFERENCE frame is identical to the NAC_AMPLIFIER_A_ELECTRICAL frame.

The X-axis corresponds to the CCD horizontal direction and the Y-axis corresponds to the CCD vertical direction (positive away from the serial register) The NAC_AMPLIFIER_BOTH_ELECTRICAL frame is identical to the NAC_AMPLIFIER_A_ELECTRICAL frame. 7.1.8 WAC_CCD_REFERENCE The WAC_CCD_REFERENCE frame is the coordinate frame relevant to all CODMAC 2 to 3 PDS image files. The WAC_CCD_REFERENCE frame is identical to the WAC_AMPLIFIER_A_ELECTRICAL frame.

The +Y axis is oriented along the solar panels and the +X is orthogonal to the high gain antenna mounting panel. The Rosetta spacecraft coordinate frame can be addressing in the SPICE system using the coordinate frame alias “ROS_SPACECRAFT”. Figure 12 The Rosetta spacecraft coordinate frame (S/C- COORDS) definition 7.2.3 Camera Frames: 7.2.3.1 NAC_CAMERA_FRAME: The NAC_CAMERA_FRAME is defined with origin at the center of the entrance aperture of the NAC camera with the +X axis along the image horizontal axis and the +Y axis along the vertical image direction. The +Z axis is defined as the right hand coordinate system defined by +X and +Y. Please note that for the NAC the +Z axis points in the opposite direction of the viewing direction. The exact transformation can be found using the CAMERA_COORDINATE_SYSTEM label group in NAC images. 7.2.3.2 WAC_CAMERA_FRAME: The WAC_CAMERA_FRAME is defined with origin at the center of the entrance aperture of the NAC camera with the +X axis along the image horizontal axis and the +Y axis along the vertical image direction. The +Z axis is defined as the right hand coordinate system defined by +X and +Y. Please note that for the WAC the +Z axis is pointed in the same direction as the boresight viewing direction. The exact transformation can be found using the CAMERA_COORDINATE_SYSTEM label group in WAC images. 7.3 Displaying the OSIRIS images The OSIRIS images are stored using the following format This structure means that the image (as is typical for PDS images) needs to be vertically flipped to be correctly displayed on a typical computer screen. On top of this the images from the narrow angle camera requires a horizontal flip to be shown with in the same geometry as the wide angle camera images. To summarize: OSINAC images: flip horizontally + flip vertically OSIWAC images: flip vertically Using these transformations the x-image axis is roughly aligned with the spacecraft y axis and the y-image axis is roughly aligned with the spacecraft x-axis. 1 8 The OSIRIS EDR and RDR PDS Labels 8.1 System Labels Label Group Namespace Datatype Unit Description Source PDS_VERSION_ID Label PDS version Fixed identifier LABEL_REVISION_NOTE String PDS label set Fixed version RECORD_TYPE Label PDS System Fixed Label RECORD_BYTES Integer Number of bytes Image in a record converter block FILE_RECORDS Integer Number of Image records in the converter file LABEL_RECORDS Integer Number of Image records in the converter PDS label header FILE_NAME String Original Image filename Converter ^IMAGE Pointer Offset of the Image image data Converter within the file (in records) ^BLADE1_PULSE_ARRAY Pointer Offset of the Image shutter blade 1 Converter position encoder data within the file (in records) Note: This field only exists if blade 1 shutter pulse data exists in the data ^BLADE2_PULSE_ARRAY Pointer Offset of the Image shutter blade 2 Converter position encoder data within the file (in records) Note: This field only exists if blade 2 shutter pulse data exists in the data SOFTWARE_DESC String Description of Image the software converter that generated the PDS file SOFTWARE_NAME String Filename of the Image image converter converter SOFTWARE_VERSION_ID String Version of the Image image converter converter SOFTWARE_RELEASE_DATE String Release date of Image the image converter converter 8.2 Mission Identification Label Group Namespace Datatype Unit Description Source INSTRUMENT_HOST_ID String ID of the Fixed instrument host INSTRUMENT_HOST_NAME String Name of mission Fixed MISSION_ID String ID of mission Fixed MISSION_NAME String Name of mission Fixed MISSION_PHASE_NAME String Name of overall Image mission phase convert er 8.3 Instrument and image Identification Label Group Namespace Datatype Unit Description Source INSTRUMENT_ID String ID of the TM instrument Either OSINAC or OSIWAC INSTRUMENT_NAME String Description of TM/Fixed instrument INSTRUMENT_TYPE String Short TM/Fixed description of the instrument DETECTOR_DESC String Description of Fixed the detector system DETECTOR_PIXEL_WIDTH Float um Width of a Fixed single pixel DETECTOR_PIXEL_HEIGHT Float um Height of a Fixed single pixel DETECTOR_TYPE String Type of Fixed detector DETECTOR_ID String ID of detector TM/Fixed DETECTOR_TEMPERATURE Float K Temperature of TM the CCD detector in Kelvin ELEVATION_FOV Float deg Full Field of Fixed view of the instrument in elevation in degrees AZIMUTH_FOV Float deg Full Field of Fixed view of the instrument in azimuth in degrees TELESCOPE_RESOLUTION Float rad IFOV of Fixed instrument in rad TELESCOPE_F_NUMBER Float Telescope F Fixed number TELESCOPE_FOCAL_LENGTH Float m Telescope focal Fixed length IMAGE_ID Integer User defined TM image ID number PROCESSING_ID ROSETTA Integer The OSIRIS DPU TM has the capability to make multiple transfers of the same set of images data (The image can for example be first transferred as a highly compressed thumbnail image for quick look purposes followed later by a transfer of the same pixel data as a less compressed version).

WARM: Pixel is marked as warm (increased and slightly varying ensitivity) – use with caution LOSSY: Pixel has seen lossy image compression NLIN: Pixel was expososed into the non linear DN range of the CCD CONV: Pixel has seen gauss convolution filtering as part of the image compression SQRT: Pixel has seen sqrt filtering as part of the image compression The general rule for the quality map is that low absolute values means good data and high absolute values mean suspect data.
