Common Interface for World Coordinate System - APE 14¶
To improve interoperability between packages, the Astropy Project and other interested parties have collaboratively defined a standardized application programming interface (API) for world coordinate system objects to be used in Python. This API is described in the Astropy Proposal for Enhancements (APE) 14: A shared Python interface for World Coordinate Systems.
The base classes that define the low- (
BaseLowLevelWCS) and high- (
BaseHighLevelWCS) level APIs are in astropy.
GWCS implements both APIs. Once a gWCS object is created the API methods will be available. It is recommended that applications use the
Common API to
ensure transparent use of
