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 12th Jan 2016 to 9th Feb 2016. The frequency of the navigation slots was of one image every five hours, with interruption by manoeuvres. From 3rd February 2016, the frequency was back to 4 images every 5 hours (2x2 rasters). 227 navigation images were taken. In addition, 289 context images and 16 calibration ones were taken, which makes a total of 532 images. There is no lost or incomplete navigation images. There is no lost context images but one context image has been taken with lost rows due to ground station problems at DSS-34. The orbiter was executing far fly-by arcs with distance ranging from 95km to 45km. The orbiter left the terminator plane for the day side. The phase angle was between 58 and 66 degrees. 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 check-out. During the comet escort phase CAM2 will only be used in the case of a failure of the nominal camera CAM1. For each image, the user can also find the FITS format of the observation in the EXTRAS directory.
