57 PyERFA is the Python wrapper for the ERFA library (Essential Routines
58 for Fundamental Astronomy), a C library containing key algorithms for
59 astronomy, which is based on the SOFA library published by the
60 International Astronomical Union (IAU). All C routines are wrapped as
61 Numpy universal functions, so that they can be called with scalar or
62 array inputs.
