sun_angdist

Name
         sun_angdist
Purpose
         calculate the angular separation between the Sun and a
         celestial body
Category
         Astronomy
Calling Sequence
         sun_angdist,time,ra_obj,dec_obj,angdist, $
                     ra_sun=ra_sun,dec_sun=dec_sun,radians=radians
Input Parameters
         time      : Date array in JD.
         ra_obj    : The right ascension of the celestial body in DEGREES.
         dec_obj   : The declination of the celestial body in DEGREES.
Optional Input Parameters
         none
Keyword Parameters
         radians   : If this keyword is set, then all output
                     variables are given in Radians rather than Degrees.
Output Parameters
         angdist   : The angular distance between the Sun and the
                     celestial body in DEGREES,
                     double precision, same number of  elements as time
Optional Output
         ra_sun
         dec_sun
Common Blocks
         none
Side Effects
         none
Restrictions
         none
Procedure
         Requires the sunpos procedure.
Example
