um512 - set the GSFC 12/66 model coefficients

subroutine  um512(tm, lbl)

Parameters:

• tm [real8,out] :: Epoch of the geomagnetic field calculation expressed in year

• lbl [character32,out] :: label of the geomagnetic field model

Description

The subroutine um512() initializes the expansion coefficients of the geomagnetic field inside the common block uc140 with the coefficients of the GSFC 12/66 model. The tm arguments specifies the epoch to which the model has to be extrapolated. The base epoch of the GSFC 12/66 model is 1960. The lbl argument returns with a string with the name of the model.
