dependent gravity model. Linear rates and
periodic terms in the time dependent gravity
model will be calculated from this time.
NOTES: See option GRVTIM for the time dependent gravity formulation.
UNITS: KM =Kilometers; M =Meters ; S =Seconds ; M/S=Meters per second
MAS=Milliarc seconds
IF CARD OMITTED: Epoch time for time dependent gravity will be zero.
