Calling Sequence

ephcheck,objcode,obs,astfile

Inputs

obs - Standard observatory code (see RdoBSCOD)

Optional Input Parameters

astfile - Raw astrometry file to read and compare to ephemeris, default
is "objcode.ast" where the input objcode is first stripped of
the leading prefix character.

Keyword Input Parameters

PLOTIT - Flag, if set will cause the information to be plotted as well.
LOWESS - If provided and greater than zero, will cause a lowess plot
