Signal removal from background
Added a function called "New_SNR()" to "postcoh.c" file. New_SNR is basically a reweighted-ranking statistics function of SNR and Chisq. The purpose is to remove signal triggers while background calculation. The threshold set for signal removal is (newsnr>8) set according to O3 sensitivity. It can be further tuned during O4 engineering run.
