RO-C-NAVCAM-3-ESC4-MTP023

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 20151117 and 20151215. The frequency of navigation slots was one image every five hours, with interruption by manoeuvres. This resulted in 128 navigation images. In addition, 269 context images were taken, which gives a total of 397 images. For one context image, rows were lost (due to an anomaly in the transfer to the spacecraft memory only occurring for context images). One context image was received with wrong time stamp due to an anomaly, but has been manually corrected from 20151123T15:25:05 to 20151124T09:37:21. The spacecraft performed far flyby arcs with distances ranging from 150km to 100km and transitioning from the dayside to the terminator. 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.
