1 UV_FCCT Compute a UV table (using a template sampling) from a list of clean components
        UV_FCCT

    Compute  a  UV  table from a list of Clean Components (for several chan-
    nels) and a reference UV table used to specify the UV sampling. This  is
    the  fast  version of UV_CCT, which uses an intermediate FFT plus resam-
    pling 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 Clean Component Table" IMAGE$

    Clean Component table from which the model UV table  must  be  computed.
    The outputs of Mapping and the task CLEAN are accepted.

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" FREQUENCY$

    New observing frequency (in MHz).  Use O to re-use the  Clean  Component
    Frequency.

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

    The  default  size  is that of the initial Clean image. This is adequate
    for standard purpose, but you may want something different.
