Type: Adverb   (Real)
Use:  SYMBOL is a general adverb to define a plotting symbol.
Null value:  0
      Null value assignment varies with task or verb.
      Standard values:
             1: Plus sign           12: Five pointed star
             2: Cross (X)           13: Star of David
             3: Circle              14: Seven-pointed star
             4: Box                 15: Eight-pointed star
             5: Triangle            16: Nine-pointed star
             6: Diamond             17: Ten-pointed star
             7: Pentagon            18: 11-pointed star

             11: Nine-gon           22: Cross (X) with gap
                                     23: Vertical line
      Numerous tasks support these values including PLOTR, STARS, and
      those tasks that plot the contents of STars files (CNTR, GREYS,
      KNTR, PCNTR, etc.)
Task:
  ALVAR.......Plots the Allan Variance statistic of a UV data set.
  ANBPL.......Plots and prints uv data converted to antenna based
              values.
  BLSUM.......Sums images over irregular sub-images, displays spectra.
  CAPLT.......Plots closure amplitude and model from CC file.
  CLPLT.......Plots closure phases as a function of time.
  ELFIT.......Plots/fits selected contents of SN, TY, SY, PC or CL
              files.
  GAL.........Determine parameters from a velocity field.
  IRING.......Integrates intensity / flux in rings / ellipses.
  MFPRT.......Prints MF tables in a format needed by modelling
              software.  SYMBOL is put in a STARS format file.
  PDPLT.......Plots selected contents of PD tables.
  PRTAN.......Prints the contents of the ANtenna extension file.
  SNBLP.......Plots selected contents of SN or CL files on a baseline
              basis.
  SNFIT.......Fits parabola to SN amplitudes and plots result.
  SNIFS.......Plots selected contents of SN, TY, SY, PC or CL files by
              IF.
  SNPLT.......Plots selected contents of SN, SY, TY, PC or CL files
              versus time
  SOUSP.......Fits source spectral index from SU table or adverbs.
  SYVSN.......Plots selected SY/TY data with SN solution values versus
              time.
  UVHOL.......Prints holography data from a UV data base with
              calibration.
  VPLOT.......Plots uv data and model from CC file
Verb:
  COSTAR......Plots a symbol at given position on top of a TV image
