Minutes
Present: Alex, Arshak, Carlos, Tyler, & ig
1/ ig described the gain QC, instruction can be found here: https://halldweb.jlab.org/wiki/index.php/Checking_the_FCAL_gains
2/ Tyler gives a status update of the tagh/tagm calibration. Tyler tuned the fitting procedure so that it will fail anymore for some counters
3/ ig shows a preliminary comparison of the eta to 2gammas angular distribution scaled by the PS scalers for Be & He targets, empty targets, and with and without B-fields. No target distribution is closer to an empty target with B-field ON. The yield when the target is present or filled is different for fields ON and OFF.
