Hello Yulou and all,

1. I have tracked down the difference between SL21d and SL23e (new dE/dx calibration)  for high dE/dx at η < -2.
2. The difference is coming from cluster size cut in time buckets ( min = 3.5, max = 16.5)   from TpcnTbk table

================================================================================

MySQL [Calibrations_tpc]> select * from TpcnTbk where elementID = 1  order by beginTime;

3. This cut is coming from analysis of collider data, and it should not be applied for fixed target data.
4. With deactivated cut high dEdx at η < -2 has appeared  (/gpfs01/star/subsys-tpc/fisyak/TbyT/TbyT_SL21d_SL23e/SL23m/st_physics_21036008_raw_3500010*.root).
5. I have deactivated this cut as today,
