RO-C-NAVCAM-3-EXT1-MTP026

Data Set history: First version Data Set Overview: The data from the Rosetta Navigation Camera (NavCam) were calibrated by Bernhard Geiger; the processing pipeline was implemented by Rafael Andres; the data set was constructed and submitted by Diego Fraga Agudo on behalf of the Planetary Science Archives (PSA). The data were acquired between 20160209 and 20160308. The frequency of navigation slots was one 2x2 raster every five hours, with interruption by manoeuvres. This resulted in 524 navigation images. In addition, 285 context and 10 calibration images were taken, which gives a total of 819 images. For one context image, rows were lost due to an anomaly in the transfer to the spacecraft memory, and for another one due to ground station problems. The spacecraft performed far flyby arcs with distances ranging from 52km to 32km and phase angles between 60 and 70 degrees. Around February 24th, a transition to terminator plane and insertion to bound orbits took place, which made it possible to decrease the distance to 17km at the end of the MTP. All images in this data set are radiometrically calibrated data taken using the imaging mode. The data set contains images using NavCam CAM1 onboard the Rosetta S/C. NavCam instrument contains a second identical camera called CAM2 but this was used mainly as a backup and the few images taken with it have not been calibrated and are not included in the Level 3 datasets. The images can be found in the DATA/CAM1 directory. For each image, the user can also find the FITS format of the observation in the EXTRAS/CAM1 directory.
