Jet Energy Corrections: reference sample for jet energy corrections and jet resolution for JERC group

This page allows you to check if your implementation of jet energy corrections heir propagation to the chsMET are correct. You'll find below a dump of 3 events for Data. For each event, information about the jets and the chsMET is given. Please, note that for JERC studies MET should be Type1 corrected with chsTypeI=L1FastJetL2L3-L1RC scheme, the result with pfTypeI=L1FastJetL2L3-L1FastJet scheme is provided for synchronization with MET group. However Type1 Corrected PF MET is pfTypeI corrected in both tables below.

You should run your code on the same input file and with the same conditions and check you obtain the same values for corrected jet and MET.
