### FLT.ZERO_SNRLO

Speeds up convergences and reduces ringing by increasing the size of the SNR mask without introducing noise

#### Description:

If non-zero values are supplied for flt.zero_snrlo and parameter "flt.zero_snr" , then the basic mask created by thresholding at the SNR value specified by flt.zero_snr is modified by expanding each un-masked " source" area down to an SNR equal to flt.zero_snrlo, without introducing any new isolated source areas. The flt.zero_snrlo should be lower than the flt.zero_snr value. [0]
