RO-C-NAVCAM-3-ESC2-MTP017

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 20150602 and 20150630. The frequency of navigation slots was one image every five hours, with interruption by manoeuvres. This resulted in 132 navigation images. In addition, 275 context and 4 calibration images were taken, which gives a total of 411 images. There were no lost or incomplete navigation images and no lost context images, but for three context images rows were lost due to ground station problems and bad weather. Another three context images were highly overexposed. The spacecraft remained in the terminator plane, with the sub spacecraft point located on the morning side. Far flyby arcs were first performed at distance ranges between 200km and 240km. Then, the closest approach distance decreased to 160km. The sub spacecraft point latitudes were located in the North for Lander communications. 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 truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
