Sagitta corrections update thanks to the work of @weitao. In particular the current update contains a uniform treatment of the sagitta correction for 2015+2016, 2017 and 2018, with 4 iterations used for all years.
Results have been presented at the past MCP meetings[1,2] and corresponding files have been copied to the calibration area: /eos/atlas/atlascerngroupdisk/asg-calib/MuonMomentumCorrections/sagittaBiasDataAll_03_02_19/
The merge request contains the input name change in MuonMomentumCorrection but additional testing of the results may be needed, before giving the new prescriptions to PA groups. Cheers, Federico
