AIPS HELP file for UV1TYPE in 31DEC18
As of Mon Feb 19 16:28:38 2018
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.
