Agenda

July 21

Looking at results from respin 2 data:

• dit - reg - lagr differences
• impact of including error bars on lagrange sensitivities
• slope plots
• slope differences per monitor from different techniques (dit vs reg)
• accumulated residuals (or, residual spread per slug RMS and averages)
• net beam corrections (3 parts and slugwise)

Tasks for next week:

• Try to zoom in on the parts where plain and eigen dit corrected asyms disagree
  • Double check the root files and slopes, etc. that there is nothing wrong in the analysis chain
  • The two methods should get identical corrected asyms
  • Verify no 1 arm running shenanigans or mislabeled data slipped in (and that run_avg == eigen_dit_run_avg_part_avgd)
• Look at where slopes disagree between dit - reg
  • Verify the corrections and/or monitorwise diff RMSs are small (so that if the slopes disagree it has negligible effect on the corrections being made)
  • Make slug_avg plots of the slope disagreements (including RMSs)
  • Make slug_avg plots of the corrections per monitor too
• Do a 12BPM Eigen Reg and Eigen Lagr comparison
  • See if the slopes agree better than the 5BPM case (where evMons 3 and 4 disagreed substantially between reg and dit)
• Provide easy to parse tables of the 5 evMon's corrections per 3 CREX parts (and make the error calculation math clear as well)
• Improve dit-reg-lagr plots
  • Add pull plots
  • Do slug averaging of these (including RMSs)
• Multipletwise and runwise diff plots being == is suspicious
  • Double check the plotting script isn't doing anything funny
  • Double check the source aggregator root file and input device list are correct
  • Double check the math by plotting the distributions by hand for some example runs

July 14

• Respin 2 outputs
• Updated eigenvector definitions
• Dit + reg + lagrange using eigenvectors
• Residual sensitivities, done correctly this time

May 19

• Respin 2: Look at dit vs. reg differences - HAPLOG
  • Look at respin2 dit-reg diff outputs
  • Checked by eye the 4+ sigma outlier miniruns
• Respin 1: 3 CREX parts’ monitorwise net corrections (and uncertainties?) - HAPLOG
  • Google Sheet
• Respin 1: Residual dithering sensitivities - HAPLOG
  • Looking at plain BPMs, run_avg sensitivities
  • Looking at eigenvector monitors, run_avg sensitivities
  • Looking at plain BPMs, cyclewise sensitivities
  • Fractional residuals (needs more work in respin2 outputs to clean up outliers) - HAPLOG
• Timescale dependent RMSs in asym->histogram filling - not discussed - HAPLOG
