Back-end DeveloperContributions:41 commits, 1 comment in 9 months
Contributions summary:Loïc primarily focused on modifying and updating the SDSS (Sloan Digital Sky Survey) query tools within the astroquery package. Their contributions involved replacing outdated URLs, fixing bugs related to data handling (specifically with `np.genfromtxt`), and adjusting image and spectra URLs. They also refactored the code for SQL queries and implemented API changes for query methods. These changes improved the data retrieval and compatibility of the astroquery package.
