Last updated on 2026-07-10 | Edit this page

This is just a copy of the information on the tags given in the tutorial. Think of this page as a quick reference sheet.

The following tags are available as of March 2026:

  • software_release
    • Software release used in the simulation. Written as a container version tag/simulation campaign naming:
    • YY.MM.v
    • E.g. 25.06.2-stable -> June 2025 software container, version 2 stable
      • Note, campaign release files will almost always be from a -stable release/container version
  • is_background_mixed
    • True/false depending upon whether sample includes any background mixing
  • data_level
    • Level of simulation data, simulation or reconstruction
  • geometry_config
    • Geometry config tag, e.g. craterlake_18x275, craterlake_5x41_He3
  • generator
    • MC event generator used to generate the simulated data
      • pythia6, pythia8, beagle, djangoh, rapgap, dempgen, sartre, lager, estarlight, eic_sr_geant4, eic_esr_xsuite, sherpa, single_particle, epic, other
  • requester_pwg
    • Defines the physics working group (PWG) that the simulated data relates to, options are:
      • edt (exclusive, diffractive and tagging), inclusive, jets_hf, semi_inclusive, ew_bsm, other
    • Can be one or more
    • Skipped for SINGLE/BACKGROUNDS
  • requester_dsc
    • Detector subsystem collaboration requester
