Python bindings for ERFA routines

PyERFA

PyERFA is the Python wrapper 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.

The project is a split of astropy._erfa module, developed in the context of Astropy project, into a standalone package. It contains the ERFA C source code as a git submodule.

Installation instructions

The package can be installed from the package directory using a simple:

$ pip install .

and similarly a Python wheel can be created with:

$ pip wheel .

Testing

For testing, one can install the packages together with its testing dependencies and then test it with:

$ pip install .[test]
$ pytest

Alternatively, one can use tox, which will set up a separate testing environment for you, with:

$ tox -e test
