SPH_RANGE_MAP

Name


      SPH_RANGE_MAP

Purpose


      Compute an array of ranges from a point on a sphere.

Category


Calling Sequence


      r = sph_range_map(lng0, lat0, res)

Inputs


      lng0 = Longitude of starting point (deg). in
      lat0 = Latitude of starting point (deg). in
      res = resolution in degrees for lat and long. in

Keyword Parameters


Keywords


        NX=nx, NY=ny Number of elements in X and Y dimensions.
          Supercedes res.

Outputs


      r = Returned distance array in degrees. out
        r covers longitudes -180 to (+180-res) and
                  latitudes -90 to (+90-res).

Common Blocks


Notes


      Note: lng0,lat0 is the point at 0 range. For example,
        if this is the subsolar point then ranges will be
        sun zenith distance in degrees.
