Generalized World Coordinate System (GWCS)

GWCS (Generalized World Coordinate System) is an Astropy affiliated package designed for managing the World Coordinate System of astronomical data. It provides a flexible and general approach to defining and transforming coordinates between detector pixels and various world coordinate systems. Tightly integrated with Astropy, it leverages Astropy's modeling, units, and coordinates frameworks to build complex transformation pipelines. The library maintains an active development pace with frequent patch and minor releases.
