TVPROF: Display PROFILE Results on the Image Display

TVPROF will display the ellipses contained in the PRF common block as a result of a PROFILE or EMAG calculation. The ellipses are drawn on the TV display. There must be an image displayed in order for TVPROF to work. This image should be the one for which the model elliptical isophotes were computed, although TVPROF has no way of knowing what image is displayed, of course. TVPROF is intended for use in conjunction with CPROF, for the purpose of inspecting and modifying the results of galaxy surface photometry calculations.
