+  Spherical coordinates to direction cosines (double precision)
+
+  Given:
+     A,B       dp      spherical coordinates in radians
+                        (RA,Dec), (Long,Lat) etc
+
+  Returned:
+     V         dp(3)   x,y,z unit vector
+
+  The spherical coordinates are longitude (+ve anticlockwise
+  looking from the +ve latitude pole) and latitude.  The
+  Cartesian coordinates are right handed, with the x axis
+  at zero longitude and latitude, and the z axis at the
+  +ve latitude pole.
