PROFILE

Marchand Manon

Over a three-month period, contributed to astropy/astropy and emscripten-forge/recipes by developing features and resolving bugs focused on astronomical data handling and interoperability. Enhanced coordinate matching in Astropy by enabling non-scalar separations and strict validation, improving both accuracy and error handling for spatial queries. Integrated VOTable COOSYS support, aligning documentation with VOTable 1.5 and refining input validation for core APIs. In emscripten-forge/recipes, added HEALPix and MOC tooling through cdshealpix and mocpy packaging, supporting advanced sky tessellation workflows. Work emphasized robust Python development, technical writing, and package management, resulting in improved reliability and cross-project compatibility for scientific software users.

Apr 1, 2025

April 2025 focused on interoperability improvements, input validation, and documentation refreshes in astropy/astropy. Implemented COOSYS integration converting VOTable coordinate systems to Astropy frames, refined 1D coordinate validation for spatial queries, and reorganized VOTable docs with MIVOT alignment to align with VOTable 1.5. These changes enhance cross-project compatibility, API clarity, and developer/docs quality.

February 2025

3 Commits • 1 Features

Feb 1, 2025

February 2025 focused on enhancing coordinate matching capabilities in astropy/astropy, improving robustness of validation, and correcting external-domain references. Delivered feature enhancements for non-scalar separations in coordinate matching, strengthened validation logic with strict-length handling, and corrected Vizier FTP domain usage in docs and samples. These changes improve accuracy, reliability, and developer experience for cross-matching workflows.
