1 UV_FMODEL Compute a UV table (using a template sampling) from a model data cube
        UV_FMODEL

    Compute a UV table from an input image (3-D data cube are allowed) and a
    reference UV table used to specify the UV sampling.  This  is  the  fast
    version  of  UV_MODEL,  which  uses  an intermediate FFT plus resampling
    rather than the direct Sin and Cos.

2 UVSAMPLE$
        TASK\FILE "Input UV Sample Table" UVSAMPLE$

    UV table used to define the UV plane sampling. U, V, date, time,  anten-
    nas  and weights are copied from this table to the model one. This table
    could be produced using the ASTRO\UV command.

2 IMAGE$
        TASK\FILE "Input .LMV Cube" IMAGE$

    Image from which the model UV table must be computed. It  should  be  in
    the  order  RA,  Dec, Velocity. This brightness of this cube must be ex-
    pressed as a main beam temperature in K.

2 UVMODEL$
        TASK\FILE "Output UV Model Table" UVMODEL$

    Output UV table, i.e. the Fourier transform of the IMAGE$ sampled on the
    coordinates specified in the sample UV table UVSAMPLE$ .

2 FREQUENCY$
        TASK\REAL "UV Model Table frequency (GHz)" FREQUENCY$

    Rest frequency of the output UV table, must be in GHz

2 LARGE$
        TASK\LOGICAL "Accurate (YES) or rough (NO) precision" LARGE$
