Agenda

• Done - BMOD run period segmentation and outliers
• Done - BMOD Sensitivity calculations
• Done - BPM Eigenvector analysis (Cameron learns some software)
• Evaluating regression vs. dithering, various diagnostics
• HAPLOG - Selecting stable BPM combos for another pass with plain BMOD, then lagrange regression, etc.

Notes

• The combination definition (coefficient of which BPMs live in orthonormal evMon eigen vectors) plots are not so useful when multiplying by the slope value - recreate these plots with just the orthonormal composition values directly
• Also the 5BPM slopes plots need to be just Draw("ap"), no connecting lines needed
• Lagrange regression would be good to pick up next, for consistency with PREX analysis
• Evaluate the dithering residuals that already were made from initial BMOD analysis and put on the HAPLOG
• Make comparisons of different analysis techniques using the difference in quadrature mean_error's method (per minirun, and per longer time scales) to see how far off two analyses are from each other
• Do a second pass of eigen vector composition stabilizing/resorting to get the remaining bits of noise to go away

Plan for next week:

• Do a segment-wise eigenvector-averaged dithering combo analysis for a direct comparison with eigenvector regression
  • Segment is a stable BMOD sensitivity time period, determined from the simple BPM set initial BMOD data (HAPLOG incoming soon)
  • Check the similarity between evMon regression and BMOD slopes calculated (averaged over various time scales)
  • Also check the composition of the evMon combos vs. time
  • Also check on residual sensitivities calculated using these slopes
