Changed the HC IA setting from 61000 to 48150 at 18:13
Looking at the first production beam currents in parity runs 13732-13733 (15:50-17:50), the Hall C charge asymmetry was leveling off at about -2500 ppm.
At 18:13, after about 23 minutes of run 13734, I changed the Hall C IA setting from 61000 to 48150, which ought to bring the asymmetry close to zero. Unfortunately, this change was just after the beam stopped to reconfigure the machine for high current beam without witness beam (https://logbooks.jlab.org/entry/4230310) so we can't check the new asymmetry yet.
