DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION :Data Set history::First version:Data Set Overview::The data from the Rosetta Navigation Camera (NavCam) were calibrated byBernhard Geiger; the processing pipeline was implemented by Rafael Andres;the data set was constructed and submitted by Diego Fraga Agudo on behalfof the Planetary Science Archives (PSA).The data were acquired between 2015-06-30 and 2015-07-28. The frequency ofnavigation slots was one image every five hours, with interruption bymanoeuvres. This resulted in 128 navigation images. In addition, 159 contextand 33 calibration images were taken, which gives a total of 320 images.Three planned navigation and three context images were not acquired due to therecovery of anomalies. One navigation image was skipped because of a startracker CCD read-out. For three context images, rows were lost due to groundstation problems.The spacecraft performed far fly-by arcs at distances between 150km and 200kmin the terminator plane and at positive latitudes of the sub-satellite point.All images in this data set are radiometrically calibrated data taken usingthe imaging mode. The data set contains images using NavCam CAM1onboard the Rosetta S/C. NavCam instrument contains a second identical cameracalled CAM2 but this was used mainly as a backup and the few images taken withit 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 theobservation in the EXTRAS/CAM1 directory.:Filename Convention::In DATA:The filenaming convention for all data levels is given by: __. ROS CAM1 YYYYMMDDThhmmss C IMG CAM2 Q LBLWhere X can be C, Q or be absent. It is present for level 3 data (C for imageand label file, Q for quality map). It is absent for level 2 products.Examples: ROS_CAM1_20160308T154502C.IMG ROS_CAM1_20160308T154502Q.IMG ROS_CAM1_20160308T154502C.LBLIn BROWSE:The filenaming convention for all data levels is given by: __C.

ROS CAM1 YYYYMMDDThhmmss FIT CAM2 LBLWhere C indicates it is a calibrated image file and F indicates it is in FITSformat.Examples: ROS_CAM1_20160308T154502CF.FIT ROS_CAM1_20160308T154502CF.LBL:Geometry Information - Coordinate System::The label files include the following geometric variables:- SC SUN POSITION VECTOR: The vector from the spacecraft to the Sun in equatorial J2000 inertial frame.- SC TARGET POSITION VECTOR: The vector from the spacecraft to the centre of the comet nucleus in equatorial J2000 inertial frame.- SC TARGET VELOCITY VECTOR: The spacecraft to comet nucleus velocity vector in in equatorial J2000 inertial frame.- TARGET CENTER DISTANCE: The distance between the spacecraft and the comet nucleus centre. (Note that also for checkout and stellar calibration images the comet nucleus distance is given here.)- SUB SPACECRAFT LATITUDE and SUB SPACECRAFT LONGITUDE: The latitudeand longitude of the sub-spacecraft point derived from the FlightDynamics body-fixed reference frame implicitly specified by theinformation provided in the comet attitude file CATT.- RIGHT ASCENSION and DECLINATION: Right Ascension and Declination ofthe camera boresight direction in equatorial J2000 inertial frame.- CELESTIAL NORTH CLOCK ANGLE: The direction of celestial north at the center of the image - measured from the upward direction, clockwise to the direction toward celestial north.- SOLAR ELONGATION: The angle between the line of sight of observation and the direction of the Sun.All geometric values are calculated for the time t : IMAGE TIME(and not START TIME).:
