AIPS HELP file for UV1TYPE in 31DEC22
As of Fri Jan 21 13:27:10 2022
Type: information only.
Information: Convolving function type 1 = Pillbox
PARM(1) = Support size in cells. 0 --> 0.5
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 1 and -1 are rectilinear (in X and Y separately), types 11
and -11 are circular (in R = sqrt(X*X+Y*Y)).
Types -1 and -11 are for single-dish use and have units of arc
seconds for PARM(1) with default = single-dish-beam_size/6.
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
SCIMG....Full-featured imaging plus self-calibration loop with
SCMAP....Interferometer imaging with Cleaning, self-calibration and
SDIMG....Single-dish imaging able to do large fields (with large
UVIMG....Grid UV data into an "image"
UVMAP....Interferometer imaging with no Cleaning, no calibration.
