      SUBROUTINE slAOPT (DATE, AOPRMS)

     - - - - - - -
      A O P T
     - - - - - - -

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

  Given:
     DATE   d      UTC date/time (modified Julian Date, JD-2400000.5)
                   (see AOPPA source for comments on leap seconds)

     AOPRMS d(14)  star-independent apparent-to-observed parameters

       (1-12)   not required
       (13)     longitude + eqn of equinoxes + sidereal DUT
       (14)     not required

  Returned:
     AOPRMS d(14)  star-independent apparent-to-observed parameters:

       (1-13)   not changed
       (14)     local apparent sidereal time (radians)
