Information: Convolving function type 5 = Spheriodal function. Parameters are: PARM(1) = Support size. 0 --> 3.0 cells PARM(2) = ALPHA. 0 --> 1.0 PARM(3) = Scale factor for support size. 0 --> 1.0 See memos by Fred Schwab for more details; large support size may have undesired results. Changing these can put divides by zero in the map plane and can reduce the degree of alias suppression. See the VLA Scientific Memo Series 123, 124, 129, and 131. See also Synthesis Imaging in Radio Astronomy, ASP Conference Series, Volume 6, pages 130-134. Types 5 and -5 are rectilinear (in X and Y separately), types 15 and -15 are circular (in R = sqrt(X*X+Y*Y)). Types -5 and -15 are for single-dish use and have units of arc seconds for PARM(1) with default = single-dish-beam_size. Tasks: BSGEO....Single-dish re-grid from pseudo az-el to RA-dec. BSGRD....Single-dish continuum beam-switched imaging and correction. CONPL....Plot aspects of the convolving functions. IMAGR....Interferometer imaging with calibration, Cleaning, and wide-field corrections. SCIMG....Full-featured imaging plus self-calibration loop with interactive editing SCMAP....Interferometer imaging with Cleaning, self-calibration and interactive editing. SDGRD....Single-dish imaging. SDIMG....Single-dish imaging able to do large fields (with large scratch files). UVIMG....Grid UV data into an "image" UVMAP....Interferometer imaging with no Cleaning, no calibration. ----------------------------------------------------------------
