View source for In-situ jet calibration (ATLAS)

[[Category:ATLAS]]
The '''in-situ [[jet]] calibration in [[ATLAS]]''' consists of two separate calibrations:

* ''<math>\eta</math> intercalibration'' changes the jet [[transverse momentum]] in data to make the data-MC response uniform as a function of the jet [[pseudorapidity]] <math>\eta</math> (i.e. changes <math>|\eta| > 0.8</math> to match <math>|\eta| < 0.8</math>)
* ''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)
