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 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 20th Oct 2015 to 17th Nov 2015. The frequency of the navigation slots was of one image every five hours, with interruption by manoeuvres. 128 images were taken. In addition 301 context images were taken, which makes a total of 429 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 bad weather over DSS65. The orbiter was approaching the comet after far excursion. It was executing far flyby arcs with distance ranging from 420km to 140km. The phase angle was around 65 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 checkout.
