1 UV_MAP
        UV_MAP :  Fast map making from UV data, using FFT

    UV_MAP makes a map from UV data by gridding  the   UV   data   using   a
    convolving  function,  and then Fast Fourier Transforming the individual
    channels.  UV_MAP can produce one beam per channel or a common beam  for
    all  channels.  In the latter case, the gridding is done only once, thus
    neglecting  frequency change between channels; this is  of  course  much
    faster.

    UV_MAP allows to shift the map center and rotate the image, by  shifting
    the  phase  tracking center and rotating the UV coordinates of the input
    UV table.

    UV_MAP produces an output LMV cube (X, Y, Velocity) and a BEAM image  or
    cube  from  the input  UV  table.  UV_MAP is an optimized version of the
    older UVMAP.

2 UV_TABLE$
        TASK\FILE "UV table" UV_TABLE$

    The UV table name.  Default extension is .UVT.  This UV  table  will  be
    shifted, rotated and sorted if necessary.
2 MAP_NAME$
        TASK\CHARACTER "Map name" MAP_NAME$

    The output map name.  Default extension is .LMV.  A beam  with  the same
    name will be produced with default extension .BEAM.
2 UV_TAPER$
        TASK\REAL "UV taper(1/e level, meters)" UV_TAPER$[2]

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

    NAtural (optimum in terms of  sensitivity)  or  UNiform  (usually  lower
    sidelobes)  weighting.  Caution:  UNiform weighting is really disastrous
    for the type of UV coverage obtained at Plateau de Bure.
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$[2]

    The map cell size. It is recommended to use identical values in X and Y.
2 UV_CELL$
        TASK\REAL "UV cell(m), for unif.  weighting" UV_CELL$[2]

    The UV cell size for uniform weighting.  Should be of the order  of half
    the dish diameter, or smaller.
2 ONEBEAM$
        TASK\LOGICAL "Make one beam (YES), or one per channel (NO)" ONEBEAM$

    For spectral  line  data,  specify  whether  a  common  beam  should  be
    generated for all channels, or one beam per channel.
2 WCOL$
        TASK\INTEGER "Weight channel" WCOL$

    The channel from which the weight should be  taken.   WCOL$  set  to   0
    implies no weighting, and is normally disastrous.
2 MCOL$
        TASK\INTEGER "First and Last channel to map" MCOL$[2]

    The first and last channel to be mapped.

2 CONVOLUTION$
        TASK\INTEGER "Convolution function [0-5]" CONVOLUTION$

    Select the desired convolution function for gridding  in  the  UV  plane
    Choices are
        0    Default (currently 5)
        1    Boxcar
        2    Gaussian
        3    Sin(x)/x
        4    Gaussian * Sin(x)/x
        5    Spheroidal
2 UV_SHIFT$
        TASK\LOGICAL "Change map center or map orientation" UV_SHIFT$

    Indicate whether map center (i.e. phase tracking center) or  orientation
    should be modified or not.

2 RA_CENTER$
        TASK\CHARACTER "Map Center RA" RA_CENTER$

    New Right Ascension of map center.
2 DEC_CENTER$
        TASK\CHARACTER "Map Center DEC" DEC_CENTER$

    New Declination of map center.
2 ANGLE$
        TASK\CHARACTER "Map Position Angle (deg)" ANGLE$

    Position Angle of the direction which will become the apparent North  in
    the map.
