CONSTELL

        [ASTRO\]CONSTELL [/DRAW [m] [l] [s]] [/NAME] [/BOUNDARIES]

    Plots in the current FRAME with the current FONT, MARKER  and  PEN,  the
    constellations,  i.e.,  the  main stars of all the constellations with a
    marker size adequately depending on the magnitude.  The options are:
     /DRAW [m] [l] [s]
     "m" will cause markers at the star's positions to be plotted
     "l" will cause the constellations outlines to be plotted
     "s" will cause the star's names to be plotted (using current centering and
         character size)
     /NAME will draw the constellation's names
     /BOUNDARIES will draw the constellation boundaries (originally constant RA
         and DEC at 1875 epoch, they are precessed to the current epoch.
         The current code is VERY slow. Use with caution.
    This command makes use of the logical name GAG_CONSTELL which points  to
    a  GILDAS  Table  containing  the stars positions and drawing codes, and
    GAG_CONST_BOUND which defines the constellation boundaries.
