Description
This is related to #59.
It would be good to have (IWBGTH) the ability to select either a single threshold (this is the current functionality) or an adaptive threshold.
The latter case could either be:
- a S/N cut depending on the noise in a given 2D image
- a S/N cut depending on the noise in a given 1D spectrum
- a spatial filter (in the style of the ASKAPsoft continuum case) to determine the local noise
- a spectral equivalent
- a "3D" equivalent, looking at a bunch of channels over a small range of frequencies.
Where the stats are calculated would depend on the single/adaptive nature of the threshold, and on what the adaptive case was.
