liking that a lot - just tried it with an Iris Nebula set of data I've just started working on - easy to run and gives a better result than BN and CC did.
One small request though, would it be possible to have an option to output the background reference mask, like CC has, so that you can check that your upper limit for background was a good choice ? (It would be nice if BN had the same option to output the mask too)
Cheers
