Subtract a continuum from a line UV data set, by fitting a baseline for each visibility. The channels to be ignored in this process (i.e. the ones including the line emission) can be specified either by the /FREQUENCY or /VELOCITY options in combination with the /WIDTH option, or by a channel list with /CHANNELS or a range (of channels, frequencies or velocities) with /RANGE.
By default, the command works on the current UV data, unless the option /FILE is specified.
With no options (or with only /FILE), the command behaves as UV_BASELINE /CHANNELS Preview%Channels. See UV_PREVIEW for details.
