1. 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 comet escort mission phase covering the
period from 2015-04-08 to 2015-05-05.
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.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)
This includes, among other files, the transmission curves for the filters,
flat fields to be applied to the raw images, etc.
And the actual IDL software source code for calibrating OSIRIS images
can be found in:
EXTRAS/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
