UV_MAP

        UV_MAP makes a map from UV data by gridding the UV data using a con-
    volving 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 can 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.
