At the beginning of shift we identified that the elevated IDX rates at 3S00 and 9S00 and NDXs throughout the end of the NL were primarily sensitive to gangphase being off crest and steering in 6R, which flattened the horizontal 7S region after a long fight, allowing us to bring gangphase back on crest. For some reason, while Hall C was down at 34 uA, the machine seems to have drifted into a better spot and the 3S00/9S00 rates were much less when they went back up to 70 uA shortly after 2100.

Figured this would be a good reference to have since our setup is stable. Omitted the AE region as that was ZPOS'd with 70 uA C beam.
