Ivan Caro enhanced overlay workflows in the SBNSoftware/icaruscode and sbncode repositories, focusing on compatibility with LArSoft v10 and improved data processing flexibility. He updated CMake build scripts and .fcl configuration files to support multiple overlay scenarios, modernizing the overlay architecture for smoother upgrades. In sbncode, Ivan introduced the OverrideRealData parameter to the CAFMaker module, enabling overlay files to be processed as Monte Carlo data with accurate POT sourcing. His work leveraged C++, CMake, and shell scripting, demonstrating depth in build systems and configuration management while reducing upgrade risk and improving data fidelity for downstream scientific analyses.
March 2025 monthly summary: Delivered key compatibility and data-handling enhancements for overlay workflows across two SBNSoftware repositories, enabling smoother upgrades to LArSoft v10 and more flexible data processing of overlay datasets. This work reduces upgrade risk, improves data fidelity for downstream analyses, and demonstrates strong cross-repo collaboration on overlay architecture and data handling. Commit-level highlights: - Overlay compatibility with LArSoft v10 in SBNSoftware/icaruscode: added new CMakeLists.txt for decoder and overlays, new .fcl configuration files for multiple overlay scenarios, and updates to OverlayProducts module and related scripts (commit d0ee09282029fdc7703333b5f112282e68461348). - CAFMaker enhancement in SBNSoftware/sbncode: introduced OverrideRealData parameter to treat overlay files as Monte Carlo data, updating POT sourcing from generator information and conditionally setting isRealData (commit f22e5e5bf78a6aa69e96426246dbaa30df77e8c4).
