  • add event preselections in strangeness derived data producer, in order to save only the collision tables from the collisions of interest,
  • add event preselections in strangeness builder, in order to save only the V0 and cascade tables from the collisions of interest,
  • Inherit preselections from the strangenessBuilderModule to prevent possible discrepancies between the event selections in the strangeness derived data producer and strangeness builder,
  • add table StraSelections to keep track of the total number of collisions and number of preselected collisions
  • adapt strangeness TOF PID task and data model to be functional with preselections
  • adapt derivedlambdakzeroanalysis in order to test the PR

Changes tested in pp, Pb-Pb (and MC) over the files:

  • for pp: /alice/data/2026/LHC26ac/570243/apass1/2340/o2_ctf_run00570243_orbit0271376640_tf0007836541_epn212/003/AO2D.root
  • for Pb-Pb: /alice/data/2025/LHC25an/568227/apass1/2250/o2_ctf_run00568227_orbit0049280448_tf0000745344_epn200/003/AO2D.root
  • for MC: /alice/sim/2026/LHC26e9/0/570143/2442/AO2D.root

Requiring NoITSROFBorder, NoTFBorder, NoSameBunchPileUp,|PVz|< 10 cm, and CBT hadron PID:

  • reduction factor 38 --> 68 in pp.
  • reduction factor 82 --> 97 in Pb-Pb.
