RO-C-NAVCAM-3-EXT3-MTP033

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 20160809 and 20160902. The frequency of navigation slots was one image every hour, with interruption by manoeuvre slots and OSIRISWAC imaging. This resulted in 292 navigation images. There was one lost navigation image and one image with lost rows, both due to bad weather at the ground station. The spacecraft was in elliptical orbits with a 20 degrees tilt with respect to the terminator plane, i.e. the phase angle ranged between 70 and 110 degrees. The pericentre was gradually reduced and the apocentre increased while maintaining a constant orbital period of 3 days: 13.7km, 7.5km, 13.7km, 6.7km, 14.4km, 6.0km, 15.1km, 5.5km, 15.5km, 5.0km, 15.9km, 4.6km, 16.2km, 4.4km, 16.4km. 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.
