Jan 1, 2026January 2026 monthly summary for gammasim/simtools focused on delivering configurable camera efficiency computation. Implemented an overwrite option for model parameters in the CameraEfficiency class, enabling users to override parameter values during camera efficiency calculations. This enhances flexibility for experimentation, benchmarking, and reproducing results across environments. The change is tracked in commit 6db4255026e89032938c8d14b1ea49fcb0fd8a44 with message: "Add the overwrite also for the case of the camera efficiency". This work strengthens the toolchain for camera performance analysis and reduces manual code edits for parameter experimentation.
