RO-C-NAVCAM-3-ESC3-MTP021

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 20150922 and 20151020. The frequency of navigation slots was one image every five hours, with interruption by manoeuvres and skipping two slots per week. This resulted in 124 navigation images. In addition, 253 context and 12 calibration images were taken, which gives a total of 389 images. For one context image, rows were lost due to bad weather at the ground station. At the start of the period, the spacecraft was in the terminator plane at 330km distance. It then performed an excursion to 1500km at a minimum phase angle of 50 degrees. At the end of the MTP, the spacecraft had returned to 420km distance and 65 degrees phase angle. 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.
