pyccl.halos.hbias.sheth99 module
- class pyccl.halos.hbias.sheth99.HaloBiasSheth99(self, *, mass_def='fof', mass_def_strict=True, use_delta_c_fit=False)[source]
Bases:
HaloBias
Implements halo bias as described in Sheth & Tormen 1999. This parametrization is only valid for ‘fof’ masses.
- Parameters:
mass_def (
MassDef
orstr
) – a mass definition object, or a name string.mass_def_strict (
bool
) – ifFalse
, consistency of the mass definition will be ignored.use_delta_c_fit (
bool
) – ifTrue
, use the fit to the critical overdensity \(\delta_c\) by Nakamura & Suto 1997. Otherwise use \(\delta_c = 1.68647\).
