1-6 A6 GCOEFS - Modifies and/or requests
the estimation of S coefficients
in the geopotential model.
7 I1 Normalization indicator. [NOTE 1] 0
= 0 values unnormalized
= 1 values normalized
= 2 values ignored
15-17 I3 Degree of S coefficient (n index). 0
18-20 I3 Order of S coefficient (m index). 0
25-44 D20.8 A priori (or starting) value of 0.
S coefficient.
60-72 D13.1 Standard deviation or fractional uncertainty 0.
of S coefficient. Coefficient will not be
adjusted if this field is zero.
If the value is less than or equal to
1.0D-5, it is used as the standard deviation
If the value is greater than 1.0D-5 it is
used as the fractional uncertainty, and the
standard deviation is computed as the
fractional uncertainty times the nominal value
of the coefficient. [NOTE 1]
NOTES:
[1] See GCOEF card for discussion of denormalization and nominal values
IF CARD OMITTED: The geopotential used will be from the gravity model
input on UNIT 12 of GEODYN-IIS unless modified by EARTH,
GCOEF, or GCOEFC cards.
