 CATEGORY:
  Astronomy
 CALLING SEQUENCE:
  addstars,name,ra,dec,rap,decp,alias
 INPUTS:
     name   - Name of the star.
     ra     - Right Ascension in radians. J2000
     dec    - Declination in radians.     J2000
     rap    - RA proper motion, "/year
     decp   - Dec proper motion, "/year
 OPTIONAL INPUT PARAMETERS:
     alias  - String with aliases for star name, each alias must be separated
                by the | character, imbedded blanks are allowed but only one
