QA  for calibration sample of  2019 AuAu 19 GeV has shown some features associated with dates when it was observed some outliers in Tpc Laser Drift Velocities (DV). During DV calibration in Run XIX it was observed that some outliers has associated with influence of lasers in sector 16. The DV difference between express calibration (Data Base entries) and recalibration done now with rejected lasers from sector 16 is shown below.
It is clear that new calibration has less outliers. As today I have deactivated old entries in Data Base and inserted new ones.
