Worked on the SegmentLinking/cmssw repository to enhance ECAL CC reconstruction by tuning out-of-time thresholds within the CMSSW configuration. Focused on adjusting the outOfTimeThresholdGain61pEB and outOfTimeThresholdGain61mEB parameters in the ecalMultiFitUncalibRecHit_cfi.py file, increasing their values from 3.0 to 12.0 to refine the sensitivity of out-of-time energy reconstruction. This configuration management effort, implemented in Python, aimed to improve ECAL timing sensitivity and overall reconstruction quality for downstream physics analyses. The work emphasized careful parameter tuning, traceable code changes, and validation of the impact on data quality, with ongoing plans for further validation and maintenance.
