 * Synopsis:    saa output_file
 *
 * Description: Writes a FITS ASCII table with the SAA contours.
 *              
 *
 * History:     07/21/98  E. Murphy   Begin work.
 *
 * References:  SAA contours from Scott Friedman 07/16/98, same contours as
 *              used in SPIKE.  Note that the contours do not extend below
 *              a latitude of 30 degrees.
