Selective persistence for BandQ doublecharm sprucing lines based on new bandq_development

Ho Sang Lee requested to merge hoslee/bandq_doublecharm_selpersist_new into bandq_development

Rebase !4284 (closed) to latest bandq_development branch

Aim to be merged with !4478

Implementing selective persistence for BandQ doublecharm sprucing line in order to reduce bandwidth to disk.

List of objects persisted + TES path:

  • All long tracks associated with same PV of double charm candidate
  • All detached long tracks (OWNPVIPCHI2 > 6)
  • All downstream tracks
  • Links between VELO tracks and PVs + VELO tracks
  • All photons
  • All merged pi0s
  • All resolved pi0s

Extra tracks/particles are all stored under the pion mass hypothesis.

Overall bandwidth change: -40% wrt persistReco=True (16MB/s to 10MB/s) across all DoubleCharm sprucing lines in local tests when running over only BandQ sprucing lines. Actual BW change can vary from line to line.
