15-17 I3 Degree of C coefficient (n index). 0.

coefficient.
60-72 D13.1 Standard deviation or fractional 0.
uncertainty of C 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 (or
(SQRT(1.0D-5) for J2) 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 GCOEFS cards.
