Name

Subroutine UM512 - set the GSFC 12/66 model coefficients

Synopsis

      REAL*8        tm
      CHARACTER*32  lbl
      
      CALL UM512 (tm, lbl)

Arguments

tm

Epoch of the geomagnetic field calculation expressed in year [in]

lbl

Label of the geomagnetic field model [out]

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. As result, the lbl argument contains a string with the name of the model.
