During November 2024, Luca Rosignoli enhanced PSF visualization capabilities in the lsst-ts/donut_viz repository by developing a new task for generating and plotting point spread functions from Zernike coefficients, supporting per-detector scatter plots and dynamic panel layouts. He centralized plotting logic and improved documentation, using Python, Astropy, and Matplotlib to ensure correctness and maintainability. In lsst-ts/ts_wep, Luca integrated these visualization features into existing pipelines and removed deprecated configurations, streamlining Rubin data processing workflows. His work improved data quality diagnostics and pipeline reliability, demonstrating depth in scientific computing, configuration management, and code refactoring within astronomy software development.
