I edited the config files for sbsvtp2/3/4/5 and increased the Latencies by 2. This is based on the analysis of data taken during owl shift showing that good GEM tracks correlated with HCAL clusters were only found after increasing the latency to 156, but at this latency setting, the GEM cut is "clipping" the coincidence window. 

See attached plot. The events with a good GEM track correlated with HCAL cluster only keep part of the good coincidence peak and the events in which ECAL is early/HCAL is late. Will test with next CODA run.
