During November 2024, John King focused on enhancing ECAL CC reconstruction within the SegmentLinking/cmssw repository by tuning out-of-time thresholds in the CMSSW configuration. He adjusted the outOfTimeThresholdGain61pEB and outOfTimeThresholdGain61mEB parameters in the ecalMultiFitUncalibRecHit Python configuration file, increasing their values to refine the sensitivity of out-of-time energy reconstruction. This targeted configuration management effort aimed to improve timing accuracy and data quality for offline analyses, supporting more reliable downstream physics results. John’s work demonstrated careful parameter tuning, thorough validation planning, and clear, traceable code changes, reflecting a methodical approach to feature delivery and configuration maintenance.
