Xiangyu Wu focused on improving data quality in the JETSCAPE/JETSCAPE repository by refining hadron filtering logic within the Qnvector writer. Using C++ and leveraging skills in data filtering and physics analysis, Xiangyu implemented status-based selection to ensure that only hadrons originating from iSS (status 11) and SMASH (status 27) were included in output data. This targeted bug fix excluded irrelevant particles, reducing noise and enhancing the precision and reproducibility of downstream analyses. The work demonstrated careful attention to data integrity and traceability, with changes clearly documented and committed, reflecting a methodical approach to scientific software engineering.
