RO-C-NAVCAM-3-ESC4-MTP022

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 20151020 and 20151117. The frequency of navigation slots was one image every five hours, with interruption by manoeuvres. This resulted in 128 navigation images. In addition, 301 context images were taken, which gives a total of 429 images. For one context image, rows were lost due to bad weather at the ground station. The spacecraft approached the comet after a far excursion. It performed far flyby arcs with distances ranging from 420km to 140km at phase angles around 65 degrees. 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. Filename Convention: In DATA: The filenaming convention for all data levels is given by: __.
