COM.ZERO_SNR_FFCLEAN

Provides alternative method for SNR masking

Description:

Setting this parameter to a non-zero value causes the SNR mask requested by parameter "com.zero_snr" to be created using an algorithm like that used by the KAPPA command " FFCLEAN" (see SUN/95), instead of using a simple thresholding of the SNR map. The parameter "com.zero_snr" gives the clipping level of the ffclean algorithm, and the parameter "com.zero_snr_hipass" gives the box size. Using an ffclean algorithm prevents the source regions within the mask being larger than the box size. [0]
