The in-situ jet calibration in ATLAS consists of two separate calibrations:

  • \eta intercalibration changes the jet transverse momentum in data to make the data-MC response uniform as a function of the jet pseudorapidity \eta (i.e. changes |\eta| > 0.8 to match |\eta| < 0.8)
  • In-situ jet energy scale: changes the jet transverse momentum in data to bring the data-MC response to unity, in bins of transverse momentum (derived in the central region, hence the need for the above)
