RO-C-NAVCAM-2-PRL-MTP003

Data Set history: This data set is version V1.1. The changes from the V1.0 are listed below: 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 GEO_NAVCAM*_INDEX and NAVCAM*_INDEX added into the INDEX directory. Data Set Overview: The data from the Rosetta Navigation Camera (NavCam) was extracted by Bernhard Geiger; the data set was constructed and submitted by Maud Barthelemy on behalf of the Planetary Science Archives (PSA). The data have been observed and measured from May, 7th to June, 4th 2014. This data set contains the first Navigation Images. They were taken at a rate of 5 images per day. The data set contains a total of 147 images. There were 28*5 140 Navigation Images plus 7 calibration images for ALICE and OSIRIS calibration (from 20140513T20:20:33 to 20140513T21:56:33). Distance from the comet are from 1818752km to 410787km. All images in this data set are raw and uncalibrated data taken using the imaging mode. The data set contains images resolved using both NavCams onboard the Rosetta S/C and the DATA directory is organised to reflect this with two sub directories: CAM1 CAM2 CAM2 directory is only present if CAM2 observations are done. After hibernation exit CAM2 was only switched on to confirm its health status in a checkout. During the comet escort phase CAM2 will only be used in the case of a failure of the nominal camera CAM1.
