Combination methods for in-situ jet calibration in ATLAS

The energy and mass of jets measured with the ATLAS detector are calibrated through a multi-step process. The residual in-situ calibration, is obtained from the data-simulation ratio of the pT balance between jets and a reference object. To obtain continuous and smooth calibration scales over the widest possible range of pT several such in-situ methods are combined. Here, the nominal and an alternative procedure for combining in-situ response ratio measurements are presented.
