Pyerfa

PyERFA provides Python bindings for the ERFA library (Essential Routines for Fundamental Astronomy), a C library based on the IAU SOFA library. It wraps ERFA's C routines as NumPy universal functions, allowing them to be called with scalar or array inputs. The library is actively maintained, with frequent patch releases addressing compatibility, especially with NumPy versions. The current version is 2.0.1.5.
