P_constants (PcK) SPICE kernel file =========================================================================== The 1991 IAU rotation and shape model constants for Mars have been extracted from the complete official NAIF PcK File "pck00004.tpc". These values originate in IAU 1991 Report and define the Mars rotation that was used by the MGS MOLA team to register MOLA instrument data products. Refer to the original complete PcK file for details on this data. Boris Semenov, NAIF/JPL, (818)-354-8136, Boris.Semenov@jpl.nasa.gov ...
