UV_MAP

        [CLEAN\]UV_MAP [CenterX CenterY Unit]  [ANGLE  AngleValue]  [/FIELDS
    FieldList]  [/TRUNCATE  Percent]  [/RANGE  Min Max Type] [/CONT [Naver]]
    [/INDEX Alpha]

    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
