[CLEAN\]UV_FILTER [/RESET] [/ZERO] [/CHANNELS Channel_List]
[/FREQUENCY List Of Frequencies] [/RANGE Min Max [TYPE]]
[/VELOCITY List of Velocities] [/WIDTH Width [TYPE]]
[/FILE FileIn [FileOut]]
"Filter" line emission, by flagging the corresponding channels. The
channels can be specified either by the /FREQUENCY or /VELOCITY options
in combination with the /WIDTH option, or by a channel list with /CHAN-
NELS or a range (of channels, frequencies or velocities) with /RANGE.
By default, channels to be filtered are flagged (weights becoming nega-
tive). Option /ZERO can be used to erase them: weights and visibilities
are set to zero, see HELP UV_FILTER /ZERO. On the contrary, option /RE-
SET can be used to unflag them (and is thus conflicting with option /ZE-
RO).
The command works on the current UV data, unless the option /FILE is
specified.
With no options (except possibly /FILE and /ZERO), the command behaves
as UV_FILTER /CHANNELS PreviewChannels. See UV_PREVIEW for details.
