DeltaT:

-------------------------------------------------------------------------------
   Computes the difference between UT1 and TT based on the Julian date.
   This model is based on observations up through 1993 and after that
   is a linear extrapolation. The equation is UT1 = TT - DT.
-------------------------------------------------------------------------------
   Form:
   dt = DeltaT( jd )
-------------------------------------------------------------------------------

   -------
   Outputs
   -------
