We reverted PSAMS from 7.5/0.55 to 8.8/-0.67, which was done last Friday in 77133. Before and after PSAMS change, we ran SCAN_ALIGNMENT and took 5+5 min asqz/sqz data. The attached figure shows that 8.8/-0.67 is better than 7.5/0.55. In parallel, A2L tuning was ongoing so the noise below 100 Hz in SQZ should be due to A2L.
