Input Run Number:

  1. External Generator (bggen): encoded in events
  2. Internal Generator (particle gun): default value
  3. RUNNO FFREAD card: change the run used for CCDB look-up (pull request to remove issued)
  4. RUNG FFREAD card: native GEANT (sets non-default internal generator run number?)

Use in HDGeant3/4:

  1. Look up calibration constants
    • Note: also affected by CCDB variation
  2. Encode in output events

Richard's proposal for HDGeant4:

  1. For calibration look-up, hierarchy of sources:
    1. RUNNO
    2. RUNG
    3. run number encoded in input events
  2. run number encoded in output events same as that used for calibration look-up

mcsmear has similar issue if user wants to control number used in calibration
