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