SSN.ZERO_SNR_LOPASS

Smooths map before making SNR mask

Description:

Setting this parameter to a positive value causes the SNR mask requested by parameter "ssn.zero_snr" to be based on a copy of the SNR map that has been low-pass filtering (i.e smoothed) to remove noise and other features smaller than the number of map pixels given by ssn.zero_snr_lopass. This may help to prevent pixels oscillating in and out of the mask on successive iterations, and thus aid smoother convergence. [0.0]
