BnoC final collections for start of 2025 data-taking

Implemented for 14th April:

BnoC top 20 line tunings

BdsToKstzKstzb - !4713 (merged) - halves bandwidth of top BnoC HLT2 Turbo line by tightening track ghostprob + chi2dof

New lines

!4235 (merged) - 6 new HLT2 Tubo lines -- assigned "bnoclow" stream

  • BdsToEtapKS_etaToGG_DD(/LL)
  • BdsToEtapKS_Gamma_DD(/LL)
  • BdsToEtapKS_Resolved_DD(/LL)
    • Bandwidth of 6 lines expected to total 5.36 MB/s (includes calo, flavour tagging, pv_tracks persitency)

!4594 (merged) - Two new Sprucing lines for 2025 data-taking

  • BuToKpPi0_Dalitz , BuToPipPi0_Dalitz
    • pi0->eegamma
      • Bandwidth estimate: 35 (KB/s)
      • Rate estimate: 0.4-0.6 Hz

Isolation update

!4701 (merged) - Update BnoC isolation options

  • Update bnoc_isolation module to include extra filtering for vertex isolation
  • Add isolation to HLT2 Turbo lines that request it (survey + extra requests)
    • Minimal cone isolation to those not requesting it (Turbo default, no extra persistency mostly): CONE_MULT CONE_PX[Y,Z]
    • Add vertex isolation to a number of lines (new information)
    • Totals 40 lines
    • No measured bandwidth change across all BnoC lines from local test

, !4730 (merged) - Add isolation reltables to 2 HLT2 Turbo lines, BdsToPpPpPmPm BdsToPpPm

, !4747 (merged) - Add isolation reltables to BnoC baryonic lines (from Turbo default, no extra persistency)

  • Bandwidth measurement: +2% in baryonic lines
  • Throughput change: < 0.1 %

Considered for future deadline

Kshh lines - !4716 (closed) - tighten ghost and chi2dof track cuts

BdsToL0L0bar lines - !4648 (closed) - tune lines

!4460 - new bdstolambdaph lines
