class halomod.concentration.Ludlow16Empirical(cosmo: hmf.cosmology.cosmo.Cosmology = <hmf.cosmology.cosmo.Cosmology object>, filter0: Optional[hmf.density_field.filters.Filter] = None, growth: Optional[hmf.cosmology.growth_factor.GrowthFactor] = None, delta_c: float = 1.686, profile: Optional[halomod.profiles.Profile] = None, mdef: Optional[hmf.halos.mass_definitions.MassDefinition] = None, **model_parameters)

Empirical Concentration-Mass relation of Ludlow et al.(2016) [1] for Planck-like cosmology.

See documentation for Bias for information on input parameters. This model has eight model parameters.

Notes

Note

The form of the concentration is described by eq(C1-C6) in [1]
