        UV_DFT :  map making from UV data

    UV_DFT makes a map from UV data using (slow) Fourier  Transform.    This
    method  introduces  no aliasing, and no grid correction, but it is slow.

    This task processes all table channels at a time.
2 UV_TABLE$
        TASK\FILE "UV table" UV_TABLE$

    The sorted, precessed UV table name.  Default extension is .UVT.  A  raw
    UV table can be sorted and precessed using UVSORT task.
2 MAP_NAME$
        TASK\CHARACTER "Map name" MAP_NAME$

    The output map name.  Default extension is .LMV
2 UV_TAPER$
        TASK\REAL "UV taper(1/e level, meters)" UV_TAPER$

    The UV taper (to be applied in both directions).
2 WEIGHTMODE$
        TASK\CHARACTER "Weight mode (NA or UN)" WEIGHTMODE$

    NAtural (optimum in terms of  sensitivity)  or  UNiform  (usually  lower
    sidelobes) weighting.
2 MAP_SIZE$
        TASK\INTEGER "Map size(2)" MAP_SIZE$[2]

    Number of pixels in X and Y.  Need not be a  power  of  two,  but   this
    would be much better for any further image processing.
2 MAP_CELL$
        TASK\REAL "Map cell(arc sec)" MAP_CELL$

    The map cell size (identical in X and Y).
2 UV_CELL$
        TASK\REAL "UV cell(m), for unif.  weighting" UV_CELL$

    The UV cell size for uniform weighting.  Should be of the order  of half
    the dish diameter, or smaller.
