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 July 2nd 2014 to Aug 1st
2014. From July 2nd to Aug 1st, the data set contains 5 images per day
for navigation, three of them with attenuation. It can be noted that
on 2014-07-18, 4 images were lost and one image partially lost due to
ground station problems. From July 25th, the Navcam images were taken
at a rate of 4 images per day, all with attenuation.
From July 30th, the Navcam images were taken one image every 30
minutes, during the comet approach sequence. This makes:
           22*5 - 4 + 8*4 + 76 = 214 navigation images.

Distances are from 42980km to 848km.

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:

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).
