In some discussions, it was suggested to explore a process where we image and self-calibrate using data from long baselines in order to filter out the difficult to deconvolve diffuse emission. Once that is completed, attempt to do a deep multi-scale clean.
Although the basics of this process were already enabled, what was not available was a way of disabling either masking or self-calibration tasks throughout the self-cal and imaging loop. This attempts to bring some of this in.
I am not entirely comfortable with the current approach, which exposes some extra CLI options where rounds can be specified as ones to skip (for self-cal) or rounds to create beam masks for (as for masking, which has always been opt-in). Perhaps the better approach is to add this go/no go options to the Options classes. But that is sort of in conflict with my eorry of putting too much flow control into what should be pure options.
