During May 2025, Jean-François Boutigny developed a vibration analysis notebook for the lsst-sitcom/notebooks_vandv repository, establishing a baseline for the M1M3 Vibration Monitor System. He used Python, Jupyter Notebook, and libraries such as Pandas and SciPy to retrieve and process VMS data, analyze power spectral density, and visualize spectrograms and displacement metrics across varying fan speeds and telescope elevations. To improve maintainability, he applied automated code formatting and readability enhancements using Ruff, refactoring imports and simplifying conditionals. His work provided a reproducible framework for future performance monitoring, supporting faster data-driven decisions and streamlined onboarding for new contributors.
2025-05 monthly summary focusing on business value and technical achievements. Key accomplishments include the delivery of a M1M3 VMS Vibration Analysis Notebook to establish a vibration baseline and assess FCU speed/elevation impacts, plus code quality improvements via Ruff that enhance maintainability without changing functionality. No major bugs reported this period; quality work completed to enable faster data-driven decisions and future analyses.
