Dataset Overview :  This CODMAC level 4 data set contains solar stray-light corrected, in-field stray-light corrected,  radiometric calibrated and geometric distortion corrected  (resampled) image data in reflectance units (normalized  and thus without unit),  acquired by the OSIRIS Narrow Angle Camera on the Rosetta spacecraft  during the COMET ESCORT 4 mission phase, covering the period  from 2015-10-20T23:25:00.000 to 2015-11-17T23:24:59.000  All header keywords are defined and described in the OSIRIS SIS: \DOCUMENT\SIS\OSIRIS_SIS_V06.PDF.   Note that the data part of the FITs files in the /DATA/FIT directory is identical to the data part of the PDS files in the /DATA/IMG directory. FITs files are delivered only for CODMAC levels 2,3, and 4 datasets.  No FITs files are delivered for CODMAC level 5 datasets.
