FLT.ZERO_SNR_HIPASS

Flatten map before making SNR mask

Description:

Setting this parameter to a positive value causes the SNR mask requested by parameter "flt.zero_snr" to be based on a copy of the SNR map that has been high-pass filtering to remove structures larger than the number of arc-seconds given by flt.zero_snr_hipass. This will in general reduce the number of source pixels in the mask. See also parameter "flt.zero_snr_ffclean" . [0.0]
