Introduction =============== This data set contains science, calibration and checkout images acquired by the OSIRIS camera system on the Rosetta mission. The images were acquired during the COMET ESCORT 1 mission phase covering the period from 2015-02-10T23:25:00.000 to 2015-03-10T23:24:59.000. For details please see: CATALOG/MISSION.CAT for a description of the Rosetta mission CATALOG/INSTHOST.CAT for a description of the Rosetta spacecraft CATALOG/OSINAC_INST.CAT for a description of the OSIRIS instrument CATALOG/DATASET.CAT for a detailed description of the dataset CATALOG/TARGETS.CAT for a description of the observed targets A detailed description of the instrument can be found in: DOCUMENT/OSIRIS_SSR/OSIRIS_SSR_V01.PDF An overview description of the calibration can be found in: DOCUMENT/CALIB/OSIRIS_CAL_PIPELINE_V01.PDF A database of calibration parameters used for image calibration can be found in: CALIB/* (See CALINFO.TXT) 2. File Formats =============== The OSIRIS images are stored as data files with embedded PDS label. The data is stored as: a. two dimensional unsigned integer (LSB_UNSIGNED_INTEGER) 16 bit data for the CODMAC level 2 data b. two dimensional intel float (PC_REAL) 32 bit data for the CODMAC level 3 to N data The data is referenced using a PDS IMAGE object. The detailed description of the data file format can be found in: DOCUMENT/SIS/OSIRIS_SIS_V01.PDF 2.1 Sofware For Reading PDS Images ================================== FWPDS is a library for accessing (and manipulating) PDS-data, and is provided in this volume (see below). But it requires IDL 6.1 (or later), and is no longer officially supported. The PDS images contained in this volume can be read by any PDS-compliant software, for example, NASAView: https://pds.nasa.gov/tools/nasa-view.shtml 3. Volume Contents ================== Files on this volume are organized into a set of subdirectories below the top-level directory. The following table shows the structure and content of these directories. In the table, directory names are enclosed in square brackets ([]). See the *INFO.TXT files in some directories for specific information on the files in that directory.
