During April 2025, Myanm worked on the astropy/astropy repository, focusing on improving the robustness of WCSAxes coordinate slicing for astrophysics data visualization. They addressed a NotImplementedError in the WCSAxes.plot_coord method that occurred after slicing coordinate systems, implementing a precondition check to ensure both latitude and longitude were present before plotting. Myanm used Python and leveraged their expertise in Astropy, coordinate systems, and testing to introduce regression tests and update documentation. This work enhanced reliability for coordinate-based plotting workflows, reduced user-facing errors, and improved test coverage, reflecting a thoughtful approach to maintaining and strengthening scientific Python libraries.
