NSSDCA ID: PSSB-00709

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Description

This description was generated automatically using input from the Planetary Data System.

Data Set Overview

This data set contains raw VIS data acquired by the DAWN mission VIR spectrometer during the Vesta Encounter phases of the DAWN mission, which covered May 3, 2011 to July 18, 2012. Changes in version 2 of this data set include: 1) Saturated data have been replaced with the CORE_HIGH_INSTR_SATURATION value. 2) The contaminated region in HAMO has been filled using the CORE_NULL value. 3) Corrections to some of the housekeeping (HK) data values. Note that Version 2.0 of the data set consists of version 3 data products (PRODUCT_VERSION_ID = 03; file names = *_3.*). The version 2 data products were not included in the PDS archive.

Required Reading

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.

Processing

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.

Data

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.

Ancillary Data

No ancillary data included in this data set.

Coordinate System

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 by 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:
