/* Module : AAPhysicalMars.cpp Purpose: Implementation for the algorithms which obtain the physical parameters of Mars Created: PJN / 04-01-2004 History: PJN / 16-09-2015 1. CAAPhysicalMars::Calculate now includes a "bool bHighPrecision" parameter which if set to true means the code uses the full VSOP87 theory rather than the truncated theory as presented in Meeus's book.
