During November 2024, Luca Rosignoli enhanced the lsst-ts/donut_viz repository by developing end-to-end PSF visualization features, including a new task for generating and plotting PSFs from Zernike coefficients with dynamic, per-detector layouts and RubinTV integration. He refactored the plotting infrastructure for consistency and centralized logic, improving maintainability and documentation. In lsst-ts/ts_wep, Luca integrated PSF Zernike plotting into existing pipelines and removed deprecated configurations to streamline workflows. His work leveraged Python, Astropy, and Matplotlib, resulting in more reliable PSF diagnostics, reduced maintenance overhead, and improved data visualization pipelines for Rubin Observatory’s scientific computing environment.
