6 years ago (stange though because make_clean_mask.py has not changed for 11months so this issue has surely been there for a long time unless im missing something and this isnt really an issue).
In the facet imaging step the pybdsf run to find sources that are then to be subtracted seems to routinely find no sources. It seems that in the make_clean_mask.py the thresholds for detection are very high with
threshisl,threshpix = 100threshisl,100threshpix
which means that make_clean_mask.py is being run with thresholds of 600 and 800 which is too high to detect sources... Therefore when doing the subtraction no sources (besides the calibrator) are subtracted.
