Asteroid Vesta SPICE PCK file, DAWN SPG 2016-09-01 Solution
===========================================================================


Pedigree and Intended Usage
--------------------------------------------------------

     This PCK file contains Vesta rotation values that were determined
     during the stereo photogrammetric analysis of Dawn images during
     the creation of the HAMO DTM (see [1]). Users of this DTM should
     also use this planetary constants kernel for SPICE based image
     processing.


Organization

     This constants file may not contain the parameter values that you
     prefer. Note that this file may be readily modified by you or
     anyone else. NAIF suggests that you inspect this file visually
     before proceeding with any critical or extended data processing.

Orientation constants for asteroid Vesta
--------------------------------------------------------

     The inertial reference frame for Vesta constants is J2000; this is
     the default reference frame for PCK orientation data.

     The epoch of the constants is J2000; this is Julian ephemeris date
     (JED) 2451545.0.

     The NAIF integer code for Vesta is 2000004. See the NAIF_IDs
     required reading for further information on NAIF integer codes.
