Bnoc isolation update: reltables method

Update to BnoC vertex isolation, include filtering on long tracks based on what was used in Run1 & Run2 (uses bnoc filter_particles) : PT>250 * MeV, MINIPCHI2=4 (cuts in stdNoPIDsPions https://lhcbdoc.web.cern.ch/lhcbdoc/stripping/config/stripping34/commonparticles/stdnopidspions.html)

Update BnoC lines based on survey and specific requests to add isolation information to set of HLT2 Turbo lines for start of 2025 data-taking

  • Affects total of 38 BnoC HLT2 Turbo lines

From previous bandwidth test results effect of adding isolation per-line is negligible to the bandwidth, and no througput regression seen there.

  • Vertex isolation is new to BnoC lines (no previous implementation available, lost information if not included now in HLT2 Turbo)
  • Cone based isolation: persist minimal set of variables for now CONE_P[X,Y,Z], CONE_MULT - intention to develop algorithm that computes remaining variables that use cone three-momentum variables offline (Charmless B->VV persist only CONE_MULT and CONE_PTASY for early studies since these are of most interest to proponents)

BW measurement: No observed changed bandwidth in BnoC lines vs bnoc_run3, also of interest results in !4319 (comment 9259506)
