TRIANGLE
Type: Adverb  (REAL(50))
Use:  Specifies the triangles to be used in closure phase and
      amplitude plotting.
Null Value:  0
      All null value means use all antennas.
Tasks:
   CLPLT.........Plots closure phase and model from CC file.
                 TRIANGLE(1) > 0 plots all closure triangles listed in
                 the adverb (16 allowed).  E.g. TRIANGLE=1,2,4,2,5,6
                 will cause CLPLT to plot triangles 1-2-4 and 2-5-6.
                 TRIANGLE(1) < 0 => plot all triangles except those
                 listed in the adverb.
   CAPLT.........Plots closure amplitude and model from CC file.
                 TRIANGLE(1) > 0 plots all closure quadrangles listed in
                 the adverb (12 allowed).  E.g. TRIANGLE=1,2,3,4,2,5,6,8
                 will cause CAPLT to plot quadrangles 1-2-3-4 and
                 2-5-6-8.  TRIANGLE(1) < 0 => plot all quadrangles
                 except those listed in the adverb.
   IMEAN.........Displays the mean & extrema and plots histogram of an
                 image.  TRIANGLE is an output adverb array listing in
                 TRIANGLE(i) the brightness level exceeded by i percent of the
                 pixels.  The histogram used to produce these values
                 encompasses the full range of intensities in the image.
