The format of all VIR data are described in detail by the SIS document located in the /DOCUMENT directory. VIR team strongly recommends reading this documentation before using the data.
This data set contains raw IR data acquired by the DAWN mission VIR spectrometer during the Ceres Encounter phases of the DAWN mission, which covered December 26, 2014 to July 01, 2016.
The following table contains a listing of VIR observations at Ceres. -----------------------------------------------------------------------Dawn Science Observations -----------------------------------------------------------------------Start Mission Activity Activity Date Phase Name Description ======================================================================== 14-12-26 CSA APPROACH Ceres Science Approach Phase -----------------------------------------------------------------------15-01-13 CSA OPNAV_001 Ride-along cubes to FC OpNav images 15-01-25 CSA OPNAV_002 Ride-along cubes to FC OpNav images 15-02-04 CSA OPNAV_003 Ride-along cubes to FC OpNav images 15-02-12 CSA RC1 Ride-along cubes to FC rotational characterization movie #1 15-02-19 CSA RC2 Ride-along cubes to FC rotational characterization movie #2 15-02-25 CSA OPNAV_004 Ride-along cubes to FC OpNav images 15-03-01 CSA OPNAV_005 Ride-along cubes to FC OpNav images 15-04-10 CSA OPNAV_006 Ride-along cubes to FC OpNav images 15-04-15 CSA OPNAV_007 Ride-along cubes to FC OpNav images ======================================================================== 15-04-24 CSR RC3 Ceres Science Rotational Characterization 3 -----------------------------------------------------------------------15-04-25 CSR RC3 RC3 Equatorial Limb 001 (South) high phase 15-04-30 CSR RC3 RC3 Equatorial Limb 002 (North) high phase 15-05-04 CSR RC3n RC3 North lit side 15-05-05 CSR RC3e RC3 Equator lit side 15-05-07 CSR RC3s RC3 South lit side -----------------------------------------------------------------------15-05-09 CTS TRANSFER_ Ceres Transfer to Survey Phase TO_Survey -----------------------------------------------------------------------15-05-16 CTS OPNAV_008 Ride-along cubes to FC OpNav images 15-05-22 CTS OPNAV_009 Ride-along cubes to FC OpNav images -----------------------------------------------------------------------15-06-05 CSS SURVEY Ceres Science Survey Phase (range ~4850 km) -----------------------------------------------------------------------15-06-05 CSS CYCLE1 Survey Cycle (orbit) 1 15-06-08 CSS CYCLE2 Survey Cycle (orbit) 2 15-06-11 CSS CYCLE3 Survey Cycle (orbit) 3 15-06-14 CSS CYCLE4 Data lost to instrument reset, all data lost 15-06-17 CSS CYCLE5 Survey Cycle (orbit) 5 VIS-Only 15-06-21 CSS CYCLE6 Survey Cycle (orbit) 6 15-06-24 CSS CYCLE7 Survey Cycle (orbit) 7 VIS-Only 15-06-27 CSS CYCLE8 Data lost to instrument reset, all data lost -----------------------------------------------------------------------15-07-01 CTH TRANSFER_ Ceres Transfer to HAMO Phase TO_HAMO -----------------------------------------------------------------------No science observation in this phase -----------------------------------------------------------------------15-08-18 CSH HAMO Ceres Science HAMO Phase (avg rng ~1950 km) -----------------------------------------------------------------------15-08-18 CSH CYCLE1 12 orbits of pushbroom nadir imaging 15-08-29 CSH CYCLE2 12 orbits of pushbroom off-nadir imaging 15-09-09 CSH CYCLE3 12 orbits of pushbroom off-nadir IR-only 15-09-20 CSH CYCLE4 12 orbits of pushbroom off-nadir imaging 15-10-01 CSH CYCLE5 12 orbits of pushbroom near nadir IR-only 15-10-12 CSH CYCLE6 12 orbits of pushbroom off-nadir imaging -----------------------------------------------------------------------15-10-23 CTL TRANSFER_ Ceres Transfer to LAMO Phase TO_LAMO -----------------------------------------------------------------------No science observation in this phase
The data in this data set are raw, CODMAC Level 2 data. As such, no processes have been applied to the data other than decompression and reformatting as cubes.
The data are in PDS format. A detailed description of the data format is given in the VIR SIS document located in the DOCUMENT directory of this data set.
The geometry items SC_SUN_POSITION_VECTOR, SC_TARGET_POSITION_VECTOR and SC_TARGET_VELOCITY_VECTOR provided in the label of the data product are relative to the Earth Mean Equator frame of J2000. SUB_SPACECRAFT_LATITUDE, SUB_SPACECRAFT_LONGITUDE are given in the PLANETOCENTRIC coordinate system. These parameters are corrected for planetary and stellar aberrations. Distances are given in km, angles in degrees.
These data are available on-line from the Planetary Data System (PDS) at:
