Caption: Fig. 3.
Intensity as a function of angular radius. The source, Mars, had an angular diameter of 12﹩\farcs﹩5 at the time of the observations. Each point corresponds to an average of measurements from several pixels. In the center of the map, the grid spacing was 9﹩\arcsec﹩. At the edge of the map, the grid spacing was 18﹩\arcsec﹩. The intensity has been normalized to 1.0 at the peak. The FWHM of the profile is 24﹩\arcsec﹩.
