Apr 1, 2025April 2025: Deliveries focused on robust, configurable data analysis capabilities in O2Physics, with emphasis on pT-bin driven data collection and streamlined nightly-test workflows. Implemented dynamic pT bin tracking in DptDpt analyses and introduced a detector-level processing path for nightly tests without event selection, aligning with reconstructed pipeline behavior and improving QC and validation capabilities. No high-severity bugs fixed this month; priority was feature delivery, stability, and reproducible configuration-driven behavior to reduce manual tuning.

Feb 1, 2025February 2025 monthly summary for AliceO2Group/O2Physics focused on delivering refined event selection, richer per-collision analytics, and stronger QC instrumentation. Implemented enhanced collision filtering and per-collision data aggregation, enabling more selective event samples and detailed Nch vs phi and momentum histograms. This included refactoring for robust per-collision processing, with careful handling of start/end of collisions. Delivered ITS dead chips tracking across multiple orbits and layers, accompanied by histograms and logic to measure time-based hadronic interaction rates for per-run QC. Per-run QC alignment was strengthened through a namespace and naming consistency overhaul in the DptDpt analysis, improving maintainability and compliance with QC conventions. All changes preserve functionality while enabling better traceability and data-driven decision-making. The work leverages C++ refactoring, histogram-based analytics, and QC-centric design patterns to increase reliability and insight across physics and detector performance data.
