; Notes:  (1) Delta-T = +67.0 seconds is "built-in" to these polynomial
;         representations of the Besselian elements.  For a different value
;         of absolute Delta-T set DELTAT = Delta-T minus 67.0.
;         (2) A correction of (+0.50", - 0.25") has been applied to the
;         latitude and longitude of the moon to compensate for the
;         displacement of the mean center of figure from the dynamical
;         center of mass.
