Compute a dirty map and beam from a UV data. UV data must have been
loaded from a UV table by command "READ UV File". UV_MAP processes sin-
gle fields as well as Mosaics.
The user can control the algorithm through SIC variables. New values can
be given using "LET VARIABLE value". For ease of use, and whenever it is
possible, a sensible value of each parameter will automatically be com-
puted from the context if the value of the corresponding variable is set
to its default value, i.e. zero value and empty string. A few variables
are initialized to "reasonable" values.
The arguments define the Map center and orientation (Projection system).
Unit can be any of DEGREE, MINUTE, SECOND and RADIAN, or ABSOLUTE. In
the latter case, CenterX should be the Right Ascension and CenterY the
Declination in sexagesimal notation. Otherwise, they are offsets from
the current projection center in the specified Unit.
AngleValue is the ** absolute ** rotation of the projection (counted
East from North as usual), which means the angle between the Celestial
North and the Y axis in the resulting image.
If no argument is given, UV_MAP uses the variable MAP_CENTER to derive
the projection system. If it is empty, it does not change it.
[CLEAN\]UV_MAP ?
Will list all MAP_* variables controlling the UV_MAP parameters
