Introduction =============== This data set contains science, calibration and checkout images acquired by the OSIRIS Narrow Angle Camera system on the Rosetta mission. The images were acquired during the COMMISSIONING mission phase covering the period from 2004-03-05 to 2004-10-17. 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/OSIRIS.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 For a quick look overview of the dataset please see: EXTRAS/AAREADME.HTM for a HTLM based browse index EXTRAS/ACTIVITY.TAB for a detailed activity overview of the mission phase A detailed description of the instrument can be found in: DOCUMENT/OSIRIS_SSR/OSIRIS_SSR.PDF An overview description of the calibration can be found in: DOCUMENT/CALIB/OSIRIS_CAL.PDF A database of usefull information about the OSIRIS instruments can be found in: CALIB/* (See CALINFO.TXT) And the actual IDL software source code for calibrating OSIRIS images can be found in: SOFTWARE/OSIRIS_CAL.ZIP 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.PDF 3.
