:Data Set history::This data set is version V1.1. The changes from the V0.0 are listedbelow: - Full size BROWSE images - FITS versions added in EXTRAS directory - label content consistent with comet phase datasets - target names and types revised, mainly for 'CALIBRATION' of V1.0 - ERRATA of V1.0 addressed and removed (image orientation and geometry keywords). - updated EAICD version:Data Set Overview::The data from the Rosetta Navigation Camera (NavCam) was extracted byBernhard Geiger; the data set was constructed and submitted by MaudBarthelemy on behalf of the Planetary Science Archives (PSA).The data have been observed and measured from 28th June 2005 to 16thMarch 2006. The data have been observed and measured during the Cruise 2phase.All images in this data set are raw and uncalibrated data taken usingthe imaging mode. The data set contains images resolved using bothNavCams onboard the Rosetta S/C and the DATA directory is organisedto reflect this with two sub directories: - CAM1 - CAM2CAM2 directory is only present if CAM2 observations are done.For each image, the user can also find the FITS format of theobservation in the EXTRAS directory.:Filename Convention::In DATA:The filenaming convention for all data levels is given by: __.

All data have been validated by ESA and an external scientific review. It has been found as expected. Any exceptions are noted by the DATA_QUALITY field in the label files.
