Dear Gene and all,

We have finished BTOF calibration for Run19 AuAu 19.6GeV data with new TPC alignment. BTOF T0 and geometry behaviour are good now and we plan to use these new parameter tables to check FXT datasets.

But we find an issue about the charged particle mass splitting for this dataset similar as previous Run21 OO 200GeV. The splitting is large in positive Eta range and small in negative Eta range. Here are the slides for Run19 19.6GeV BTOF calibration in the attachment together with previous Run21 OO 200GeV report using this link:https://drupal.star.bnl.gov/STAR/system/files/VPD_BTOF_Calibrations_OO_Chenliang_0412_SC.pdf .

And this is the Drupal link for Detailed QA report: https://drupal.star.bnl.gov/STAR/system/files/tofCalibSummary_Run19_AuAu19GeV_startless_newalign_p1.pdf

Sincerely,

Chenliang Jin
