python3-erfa 1.7.1.1+ds-2 (amd64 binary) in ubuntu hirsute

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