        Smooth by NC channels a UV data set. UV_SMOOTH differs from  UV_COMPRESS
        because  it  keeps the original spectral sampling. The resulting UV data
        is thus oversampled by NC channels.

        Unless the /ASYMMETRIC option is present, the smoothing is symmetric, to
        ensure that the spectral sampling is preserved. This is implicit when Nc
        is odd, but for even values of Nc, it is done by smoothing by Nc+1 chan-
        nels,  and  giving  the  edge  channels  of the smoothing kernel a half-
        weight. The effective bandwidth of each smoothed  channel  is  still  Nc
        times the original one.

        As a result, UV_SMOOTH 2 is equivalent to a Hanning smoothing.

        With no /FILE option, the current UV table obtained by READ UV is resam-
        pled.  All further UV commands work on the "Resampled"  UV  table.   The
        "Resampled"  UV  table is a simple copy of the original one after a READ
        UV command, or after a UV_RESAMPLE or UV_COMPRESS commands with no argu-
        ments and no options.

        With  the /FILE option, the UV data is read from file FileIn and the re-
        sampled output is written in file FileOut.
