RO-C-NAVCAM-3-EXT2-MTP030

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 20160531 and 20160628. The frequency of navigation slots was one 2x2 raster every five hours, with interruption by manoeuvres. 524 navigation images were taken. In addition, 8 context and 12 calibration images were acquired, which gives a total of 544 images. For one navigation image, rows were lost due to bad weather or ground station problems. The spacecraft was at 17km distance at the beginning of the period. Then it performed two half orbits on the dayside with a minimum phase angle of 45 degrees for mapping purposes. Afterwards it went into an 28x14km elliptical orbit in the terminator plane. 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.
