Hi,

Just confirming that these runs were impacted by the VPD coincidence scaler (use in correcting for TPC SpaceCharge in the initial calibration) being zero. Other scalers seemed to be OK, so the data may still be usable once a different SpaceCharge calibration is completed.

Thanks,

3). Runs 23107033 – 038; have TPC hit positions skewed to positive x (along the padrows), especially in the iTPCs. Implies a space-charge correction error.
