SOURCE

        [ASTRO\]SOURCE [name [...]] [/DRAW [m]  [l]  [s]  [f]]  [/ALTERNATE]
    [/SUN] [/FLUX Fmin Fmax]

    Compute the coordinates of a Source from the  Current  catalog.   If  no
    name  is  specified,  all  sources  of the catalog are selected.  Source
    coordinates may also be specified in  the  command  line,  in  the  same
    format as the catalog file.  The /DRAW option is used to draw the source
    name on the plot at its  current  position  (Azimuth,  Elevation).   The
    source   coordinates   (RA,  DEC,  Azimuth  and  Elevation  at  time  of
    computation) are printed  on the screen, as well  as  the  line-of-sight
    components  of the velocities of the Solar System Barycenter G (relative
    to the Observatory) and of the Local Standard of Rest (relative  to  G).
    Both velocities are in km/s, positive if the distance is increasing.

    Arguments to /DRAW may be LINE, MARKER, SYMBOL, or FULL, as for  command
    PLANET:
      LINE   will draw a line from the previously computed position
             (SOURCE or PLANET)
      MARKER will draw a marker (GreG style defined by GREG\SET MARKER)
             at the computed position
      SYMBOL will draw the source name in capitals at the computed position
      FULL   will combine MARKER and SYMBOL (the name will be offset
             one marker size above the computed position).
    If several arguments are given they will be used in sequence.

    /ALTERNATE will direct the search to the Alternate catalog.

    /SUN will also list the sun avoidance limits

    /FLUX Fmin Fmax will select only sources  with  flux  densities  in  the
    specified  range. Marker sizes will be proportional to the (logarithm of
    the) flux.

    /PRINT option will suppress the printing of Az and  El,  and  print  the
    source characteristics as in catalog instead.
