halomod.bias.TinkerSD05

class halomod.bias.TinkerSD05(xi_dm: ndarray, **model_parameters)

Bases: ScaleDepBias

Scale-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).

bias_scale()

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.
