1-6 A6 GCOFCT - Requests application or
adjustment of the C gravity
coefficient for the time period
defined below.
25-44 D20.8 Begin time of time period gravity
45-59 D15.3 End time of time period gravity
NOTE [l]: Time period gravity is introduced by groups of input cards
where one group contains information about one discrete
period of time. Therefore one needs as many groups as the
number of discrete times where gravity coefficients are
being replaced or adjusted. These groups follow the stream
of the original gravity field coefficients and they have the
following structure:
GCOFCT or GCOFST including beginning and end of time period,
GCOEFC or GCOEFS respectively (as many as desired) with
information about replacing value or adjustment and,
GTPEND denoting the end of information for this time period.
