Elle Shaw contributed a targeted bug fix to the simonsobs/sotodlib repository, focusing on the pointing model’s azimuth calculation. She addressed errors arising from azimuth values wrapping around 2π by refining the correction logic to use modulo arithmetic, ensuring the corrected azimuth remained close to the original input and reducing calculation errors. Working primarily in Python, she applied her expertise in astrophysics, coordinate systems, and numerical computation to enhance pointing stability and data quality. The update included minor code hygiene improvements, with a clear commit history to support quality assurance and future validation, reflecting a thoughtful and precise engineering approach.
