SLA_AOPPAT - Update Appt-to-Obs Parameters   

ACTION:
Recompute the sidereal time in the apparent to observed place star-independent parameter block.

CALL:
CALL sla_AOPPAT (DATE, AOPRMS)

GIVEN:

DATE D UTC date/time (Modified Julian Date, JD-2400000.5)
AOPRMS D(14) star-independent apparent-to-observed parameters:
(1-12) not required
(13) longitude + eqn of equinoxes + ``sidereal $\Delta$UT'' (radians)
(14) not required

RETURNED:

AOPRMS D(14) star-independent apparent-to-observed parameters:
(1-13) not changed
(14) local apparent sidereal time (radians)
