: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 2015-01-13 and 2015-02-10. The frequency ofnavigation slots was one 2x2 raster every five hours, with interruption bymanoeuvres. This resulted in 524 navigation images. In addition, 170 contextimages were taken, which gives a total of 694 images.One executed navigation raster (starting at 2015-01-18T10:47:06) was lost atdownlink due to bad weather. For two further navigation images and one contextimage, rows were lost due to ground station problems and bad weather. Onecontext image was lost entirely for the same reason.At the beginning of the period the spacecraft was in bound terminator orbitsat 28km distance. A transition to hyperbolic arcs started on February 4th witha far fly-by arc reaching a distance of 140km on February 7th, roughly in theterminator plane.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).:
