5.3.5 Parameter interactive

If interactive=True is set, then an interactive window will appear at various “cycle” stages while you clean, so you can set and change mask regions. These breakpoints are controlled by the npercycle sub-parameter which sets the number of iterations of clean before stopping.

Note that npercycle is currently the only way to control the breakpoints in interactive clean.

For spectral cube imaging, it is often easier to deal with each channel in turn, rather than cleaning all channels in each cycle. We therefore provide the chaniter=True option under ’mode’, where it will clean a channel fully before moving to the next one. You will set masks for each channel.

See the example of interactive cleaning in § 5.3.14.
