Agenda
- Cameron: CREX Pedestal update and cross checked new maps
- Cameron: update on respin-2 - finished setting up
- Changed from 1357 "Good" production runs to 1392 (35 net newly deemed Good runs) and updated labels in RCDB
- Updated cuts on ~40 individual runs and the final week of cuts too, to accomplish that
- Improved burp cut implementation
- Changed PMT pedestals to using beam off
- Updated BPM and BCM pedestals with most up to date bcm_an_us vs. unser reference (log)
- Added respin1-based BMOD slopes and stable eigenvector inputs for subsequent eigenvector based regression
- Added some more AT vs. main detector combos for additional AT analyses
- Test case, compare runs 6330, 6331, 6332 between respin 1 and 2 to eachother:
- No change in number of events in root files
- ~400 new entries pass cuts in respin2
- Change in Aq mean ~0.04 ppb for the same set of data
- But 63 ppb change due to additional entries included (this was a no-Aq feedback time period, mean Aq is 1812 ppb -> 1749 ppb)
- 0.2 ppm shifts in regressed mean for these 3 runs (out of ~2ppm signal ~ few percent shift - needs to be followed up on with the full datasets)
