Description:
This
routine recomputes the sidereal time in the apparent to observed place star-independent parameter
block.
Invocation
void palAoppat( double date, double aoprms[14] );
Arguments
date =
double (Given)
UTC date/time (modified Julian Date, JD-2400000.5) (see palAoppa description for
comments on leap seconds)
aoprms = double[14] (Given & Returned)
Star-independent
apparent-to-observed parameters. Updated by this routine. Requires element 12 to be the longitude
eqn of
equinoxes
sidereal DUT and fills in element 13 with the local apparent sidereal time (in radians).
