Data Set Overview:
======================================================================

The data from the Rosetta Navigation Camera (NavCam) was extracted by
Bernhard Geiger; the data set was constructed and submitted by Maud
Barthelemy on behalf of the Planetary Science Archives (PSA).

The data have been observed and measured from May, 7th to June, 4th
2014. This data set contains the first Navigation Images. They were
taken at a rate of 5 images per day. The data set contains a total of
147 images. There were 28*5 =140 Navigation Images plus 7 calibration
images for ALICE and OSIRIS calibration (from 2014-05-13T20:20:33 to
2014-05-13T21:56:33).

Distance from the comet are from 1818752km to 410787km.

All images in this data set are raw and uncalibrated data taken using
the imaging mode.  The data set contains images resolved using both
NavCams onboard the Rosetta S/C and the DATA directory is organised
to reflect this with two sub directories:
 - CAM1
 - CAM2
For each image, the user can also find the FITS format of the
observation.

Filename Convention:
======================================================================

The filenaming convention for all data levels is given by:

              ROS     CAM1    YYYYMMDDThhmmss       IMG

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 latitude
and longitude of the sub-spacecraft point derived from the Flight
Dynamics body-fixed reference frame implicitly specified by the
information provided in the comet attitude file CATT.
- RIGHT ASCENSION and DECLINATION: Right Ascension and Declination of
the 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).
