1. Introduction
===============

  This data set contains science, calibration and checkout images
  acquired by the OSIRIS Wide Angle Camera system on the Rosetta
  mission.

  The images were acquired during the CRUISE 4-1 mission phase
  covering the period from 2008-01-28 to 2008-08-04.

  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. Volume Contents
