## Agenda

- Relaunch BMOD + beam corrections meetings, specifically for looking at CREX data from respin1 and going forward

## Notes

- Cameron has generated BMOD sensitivity, alpha/delta, and slope calculations and plots from respin1 data on the ifarm (using the same tools as prompt analysis had been using, but with more care to get the details right and all useful data stored in rootfiles)
- Output folder structure: http://ace.phys.virginia.edu/HAPPEX/4427
- Initial look at plots: http://ace.phys.virginia.edu/HAPPEX/4432

- Next steps:

- Clean up outliers and determine run ranging to produce slopes
- Calculate residuals per cycle's slopes, per run's averaged slope, and per runrange averaged slopes
- Produce corrected asymmetries for comparison with regression (note that CREX part 1 of 3 needs more attention, as BPM 1X is too correlated in regression, and causes problems for BMOD as well, in addition to BPM 1X having a questionable YP wire)
- Determine more ideal BPM combos for additional static-eigenvector analyses
- Lagrange analysis
- Minirun-wise eigenvector calculation analysis

Victoria has a CREX parts 1 and 2 of 3 set of runranges here (similar to the PREX set here), where neighboring slugs are assumed to split, blue has an internal split, and grey has no split. Orange means outlier.
