RO-C-NAVCAM-2-EXT3-MTP035

Data Set history: This data set is version V1.1. The changes from the V1.0 are listed below: correction in min/max pixel value which affected some images updated EAICD version ERRATA of V1.0 addressed and removed (image orientation and geometry keywords). 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 26th Sep 2016 to 30th Sep 2016, end of the Rosetta mission. The frequency of the navigation slots was of one image every hour. with interruption by manoeuvres. 51 navigation images were taken. The last image was taken on 30th Sep at 00:59:10. There is no lost or incomplete navigation images. The orbiter exited from elliptical orbits. It went into hyperbolic arc with distances ranging from 17km to 23km and a minimum phase angle of 38 degrees. Then it executed its final descent to the comet nucleus surface. 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.
