Can help to remove bowls around sources by increasing the size of the SNR mask
without introducing noise AST.ZERO_SNRLO
"
ast.zero_snr"
, then the basic mask created by thresholding at the SNR value specified by ast.zero_snr is
modified by expanding each un-masked "
source"
area down to an SNR equal to ast.zero_snrlo, without
introducing any new isolated source areas. The ast.zero_snrlo should be lower than the ast.zero_snr value.
