wcosmo.taylor.flat_wcdm_pade_coefficients(w0=-1, zpower=0, *, xp=<module 'numpy' from '/usr/share/miniconda/envs/test/lib/python3.13/site-packages/numpy/__init__.py'>)[source]#

Compute the Pade coefficients as described in arXiv:1111.6396. We make two primary changes:

  • allow a variable dark energy equation of state \(w_0\) by changing the definition of \(x\).

  • include more terms (17) in the Taylor expansion.

Parameters:
w0: array_like

The (constant) equation of state parameter for dark energy

Returns:
p, q: array_like

The Pade coefficients
