We've followed Camilla's suggestion to run the PSAMs scan script with a smaller step size. 814908
In userapps/sqz/h1/scripts/SCAN_PSAMS.py I've edited lines 267 and 269 so that PSAM_ZM4_LIST = [5.6, 5.7, 5.8, 5.9, 6, 6.1, 6.2, 6.3, 6.4] PSAMS_ZM5_LIST = [-0.7, -0.6, -0.5, -0.4, -0.3, -0.2, -0.1] . We will let this run until noon, and see how many points it gets.
The script ran for a while then had an error, so we got some of this data (see attachment). The error is probably due to the way I edited the lists.
Traceback (most recent call last):

The plots created are attached and in /sqz/h1/scripts/PSAMS_data/PSAMS_SCAN/250102103351/ as SQZ_DB_fit.png and heatmap.png. No clear patterns seen when looking at plots of range/BLRMs data. From the heatmap, ZM4 at 5.2V or 6.0V with ZM5 -0.6V is best. Current is 6.0V/-0.4V so the only suggested change would be to decrease ZM5 from -0.4V to -0.6V.
Comparing our SQZ_BD_fit to LLO's (LLO#72749) our BLRMS seem to oscillate when LLO's don't. Maybe we need to adjust our BLRMs filtering to improve our SQZ DB fits.
