1. There was a 15-20 mV offset in the PS 740 module dedicated to TS (total sum) signals for group 5-8. The offset was brought back to zero. The offset in the PS 740 for fanning out the tagger is within 5mV.
2. The CAMAC discriminator (in the RHRS 2nd floor) in ROC 1 slot 20 has only one signal plugged in which is the gas-cherenkov signal dedicated to pvdis setup. Changed the threshold of that discriminator from 30 mV to 40 mV. This can be controlled remotely. The name of this discriminator is "PREX_r_disc" in the code "trigger_right.map".
