onepower.hod.HaloOccupationDistribution

class onepower.hod.HaloOccupationDistribution(cosmo=None, mass=None, dndlnm=None, halo_bias=None, z_vec=None, hod_settings=None, **model_parameters)

Base class for Halo Occupation Distribution (HOD) models. This class provides the framework for computing various properties of galaxies within dark matter halos.
