Sep 1, 2025September 2025: Delivered documentation refinements for calibration_devices and flasher schemas in gammasim/simtools, and expanded test coverage for the simtel writer. Key changes include updated descriptions for calibration_devices, flasher angular distribution, flasher_exp_decay_time, and flasher_external_trigger, as well as tests asserting minsep and width in generated content. No critical bugs fixed this month; these efforts reduce configuration misunderstandings and improve downstream data reliability. Tech stack leveraged: YAML/schema documentation, Python-based tests, and Git-based workflow, reinforcing maintainability and collaboration.

May 1, 2025May 2025 monthly summary for gammasim/simtools: Delivered a robust sequential execution framework across core simulation runners (CORSIKA, sim_telarray, multipipe_corsika, shower_array_simulator) with tests and refined help text, enabling deterministic runs and easier testing. Implemented run_number_offset and related wiring to support scalable batch simulations and standardized run-number handling in the HTCondor script generator. Updated NSB usage to the actual half-moon NSB model in multipipe components, and performed a database version upgrade with an accompanying changelog. Standardized file naming for inputs, outputs, and ray tracing resources to improve traceability and reproducibility, with corresponding test/resource updates. Added documentation enhancements and a changelog entry. Fixed critical issues including CORSIKA log non-Unicode handling and various code quality improvements, supported by expanded unit tests and lint-friendly refactors. Overall, these changes reduce operational risk, accelerate batch runs, and improve data traceability across the simulation pipeline.
