Transfer function from Viel 2005 (which is exactly the same as Bode et al. 2001).

Formula from Bode et. al. 2001 eq. A9.

Parameters:

• mx (float) – Mass of the particle in keV

• cosmo (hmf.cosmo.Cosmology instance) – A cosmology.

• z (float) – Redshift.

• **model_parameters (unpack-dict) –

  Parameters specific to a model. Available parameters are as follows. To see the default values, check the _defaults class attribute.
