Maximilian Korwieser enhanced TPC Quality Control workflows in the AliceO2 and QualityControl repositories by implementing robust primary vertex (PV) handling features. He introduced a dedicated PV position setter and integrated PV coordinates into track propagation, improving the accuracy of DCA-based quality metrics. Leveraging C++ and calibration techniques, Maximilian enabled retrieval of PV positions from the CCDB with a monitoring toggle, allowing for flexible and reliable PV management. His work focused on maintainable code and traceability, addressing the need for precise PV-dependent data processing in physics software. These updates provided a more reliable foundation for downstream quality control analyses.
