void ephparms	(	double	t,
		double *	xls,
		double *	gs,
		double *	xlm,
		double *	omega
	)

This subroutine computes ephemeris parameters used by other Mission Operations routines: the solar mean longitude and mean anomaly, and the lunar mean longitude and mean ascending node. It uses the model referenced in The Astronomical Almanac for 1984, Section S (Supplement) and documented and documented in "Exact closed-form geolocation algorithm for Earth survey sensors", by F.S. Patt and W.W. Gregg, Int. Journal of Remote Sensing, 1993. These parameters are used to compute the solar longitude and the nutation in longitude and obliquity.

Parameters

t	Time in days since January 1, 2000 at 12 hours UT
xls	Mean solar longitude (degrees)
gs	Mean solar anomaly (degrees)
xlm	Mean lunar longitude (degrees)
omega	Ascending node of mean lunar orbit (degrees)
