halomod.bias.TinkerSD05¶
- class halomod.bias.TinkerSD05(xi_dm: ndarray, **model_parameters)[source]¶
Bases:
ScaleDepBiasScale-dependent bias from Tinker 2005.
Notes
Defined in [1] as
\[\sqrt{\frac{(1 + a\xi)^b}{(1 + c\xi)^d}}\]with the fitted parameters
(a,b,c,d)=(1.17, 1.49, 0.69, 2.09).References

- bias_scale()[source]¶
Return the scale dependent bias as a function of r.
The scale-dependent bias is a function of the dark matter correlation function, and the length of the returned array should be the same size as the instance
xi_dm.
- classmethod get_models() Dict[str, Type]¶
Get a dictionary of all implemented models for this component.
