pyccl.bcm.bcm_model_fka(cosmo, k, a)[source]

The BCM model correction factor for baryons.

Note

BCM stands for the “baryonic correction model” of Schneider & Teyssier (2015; https://arxiv.org/abs/1510.06034). See the DESC Note for details.

Note

The correction factor is applied multiplicatively so that P_corrected(k, a) = P(k, a) * factor(k, a).

Parameters:
  • cosmo (Cosmology) – Cosmological parameters.
  • k (float or array_like) – Wavenumber; Mpc^-1.
  • a (float) – Scale factor.
Returns:

Correction factor to apply to the power spectrum.
Return type:

float or array_like
