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% of the pixels. The histogram used to produce these values encompasses the full range of intensities in the image. ----------------------------------------------------------------
