NAME: dmstorad PURPOSE: (one line) Convert from degrees, minutes, and seconds to radians. DESCRIPTION: CATEGORY: Astronomy CALLING SEQUENCE: dmstorad, sign, deg, min, sec, radians INPUTS: sign : Sign associated with the inputs. Must be -1, or +1. deg : Degrees. No restrictions. min : Minutes. 0 <= min < 60. sec : Seconds. 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: The input declination is in four parts. The sign is carried as a separate value, to make angles near zero behave correctly. MODIFICATION HISTORY: Copyright (C) 1987, by Marc W.
