Update of muon showers line after retraining the BDT with HLT1_filtered data

Retraining of the BDT for the muon detector showers line Hlt2QEE_MDS_BDT_nHits with HLT1 filtered data to solve MC/data differences.

We tried to maintain reasonable bandwidth levels without the current prescale of the Hlt2QEE_MDS_BDT_nHits line (0.01) with two distinct processing lines:

  • Full-stream – for background studies (a higher cut on the BDT was imposed).
  • Turbo – to ensure signal retention if the full-stream cut is too high.

This merge request is associated with the approval of Update of muon-showers weights, which updates the BDT weights after retraining with HLT1-filtered data.

BANDWIDTH TESTS:

We conducted the QEE bandwidth test using 100.000 HLT1-filtered events:

  • Old BDT (currently in master prescaled to 0.01)

    • BW: 867.67 MB/s
    • Rate: 36 out of 100000 -> 464.28912 kHz
  • New BDT (TURBO LINE AND FULL-STREAM LINE)

    • BW: 871.49929 MB/s
    • Rate Turbo: 39 out of 100000 -> 502.97988 kHz
    • Rate Full-stream: 32 out of 100000 -> 412.70144 kHz
