NAME: hmstorad PURPOSE: (one line) Convert from hours, minutes, and seconds of Right Ascension to radians. DESCRIPTION: CATEGORY: Astronomy CALLING SEQUENCE: hmstorad, hour, min, sec, radians INPUTS: hour : Hour. 0 <= hour < 24. min : Minute. 0 <= min < 60. sec : Second. 0.0 <= sec < 60.0. If more than one of these are vectors, they must be the same length. A mixture of scalar and vector input parameters is equivalent to all three inputs being vectors: The scalar inputs are treated as replicated vectors. OPTIONAL INPUT PARAMETERS: KEYWORD PARAMETERS: OUTPUTS: radians : Converted angle in radians. COMMON BLOCKS: SIDE EFFECTS: RESTRICTIONS: PROCEDURE: MODIFICATION HISTORY: Copyright (C) 1987, by Marc W. Buie Version dated 87/6/3 Ported by Doug Loucks, Lowell Observatory, August 12, 1993, from the C-Language version written by Marc Buie. 2005/08/23 - MWB, minor modification to ensure full double precision calculation regardless of input data type.
