AST_GETREFPOS

Return the reference position in a specified celestial coordinate system

Description:

This routine returns the reference position (specified by attributes RefRA and RefDec) converted to the celestial coordinate system represented by a supplied SkyFrame. The celestial longitude and latitude values are returned in radians.

Invocation

CALL AST_GETREFPOS( THIS, FRM, LON, LAT, STATUS )

Arguments

THIS = INTEGER (Given)
Pointer to the SpecFrame.
FRM = INTEGER (Given)
Pointer to the SkyFrame which defines the required celestial coordinate system. If AST__NULL is supplied, then the longitude and latitude values are returned as FK5 J2000 RA and Dec values.
LON = DOUBLE PRECISION (Returned)
The longitude of the reference point, in the coordinate system represented by the supplied SkyFrame (radians).
LAT = DOUBLE PRECISION (Returned)
The latitude of the reference point, in the coordinate system represented by the supplied SkyFrame (radians).
STATUS = INTEGER (Given and Returned)
The global status.
