Legend:

GMT cluseter finder (StGmtRawMaker, StGmtClusterMaker, StGmtAlignmentMaker, StGmtUtil) has been modified (StGmtRaw25Maker, StGmtMatchMaker) in order to use the first two timebins for pedestal suppression. In old version pedestals were calculated as running average over the first 5 events. Both (old and new) versions are storing GMT hits on MuDst. The analysis below is done based on these muDst strored GMT hits.
dY (ρφ) and dZ are differences between the track prediction on GMT module and GMT hit. The production has been done using daq-files kept on HLT farm. Production version TFG25b.

Cosmics 2019 - 2024 have been used for GMT alignment with new TPC alignment (CorrZ).

2002Y has been processed with old Tpc alignment (CorrY) and Space Charge Corrections for old Tpc Alignment.

The differnece in dY between old and new Tpc aligments with the same (old alignment) Space Charge distortions is ±0.5 cm for all GMT modules (~2 mrad). "+" for West and "-" for East TPC halves.
