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