 # heuristics for switching between calonly and calflag
 # heuristics to switch from combine=spw to combine=''
 # switch heirarchy of selfcal_library such that solint is at a higher level than vis. makes storage of some parameters awkward since they live
 #    in the per vis level instead of per solint
-# clean final image with appropriate RMS noise level derived empirically, like self-cal loops, rather than theoretical
 # possibly add heuristic to switch from nterms=1 to nterms=2 in high DR cases
