RO-C-NAVCAM-3-EXT3-MTP035

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 20160926 and 20160930, the end of the Rosetta mission. The frequency of navigation slots was one image every hour, with interruption by manoeuvres. The last of 51 navigation images was acquired on September 30th at 00:59:10. The spacecraft exited from elliptical orbits and went into hyperbolic arcs with distances ranging from 17km to 23km and a minimum phase angle of 38 degrees. Finally, it descended to the comet nucleus surface. 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: __. ROS CAM1 YYYYMMDDThhmmss C IMG CAM2 Q LBL Where X can be C, Q or be absent.
