/* *+ * Name: * palAmp * Purpose: * Convert star RA,Dec from geocentric apparaent to mean place. * Language: * Starlink ANSI C * Type of Module: * Library routine * Invocation: * void palAmp ( double ra, double da, double date, double eq, * double *rm, double *dm ); * Arguments: * ra = double (Given) * Apparent RA (radians) * dec = double (Given) * Apparent Dec (radians) * date = double (Given) * TDB for apparent place (JD-2400000.5) * eq = double (Given) * Equinox: Julian epoch of mean place. * rm = double * (Returned) * Mean RA (radians) * dm = double * (Returned) * Mean Dec (radians) * Description: * Convert star RA,Dec from geocentric apparent to mean place.
