UV_SMOOTH

        [CLEAN\]UV_SMOOTH Nc [/ASYMMETRIC] [/FILE FileIn FileOut]


    Smooth by NC channels a UV data set. UV_SMOOTH differs from UV_COMPRESS  be-
    cause 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 en-
    sure  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  channels,
    and  giving the edge channels of the smoothing kernel a half-weight. The ef-
    fective 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 resampled.
    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 arguments and no op-
    tions.

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