Description [src] 

final class NumCosmo.GalaxyHODZheng07 : NumCosmo.GalaxyHOD
{
  /* No available fields */
}

Zheng et al. (2007) halo occupation distribution.

Concrete NcGalaxyHOD with the five-parameter occupation of Zheng et al. (2007). The mean central occupation is $$\langle N_\mathrm{cen} \rangle = \frac{1}{2}\left[1 + \mathrm{erf}\left( \frac{\log_{10} M - \log_{10} M_\mathrm{min}}{\sigma_{\log M}}\right)\right],$$ and the mean satellite occupation is $$\langle N_\mathrm{sat} \rangle = \left(\frac{\max(0, M - M_0)}{M_1} \right)^{\alpha},$$ with $M_0 = 10^{\log_{10} M_0}$ and $M_1 = 10^{\log_{10} M_1}$.

Ancestors

Constructors

nc_galaxy_hod_zheng07_new

Creates a new NcGalaxyHODZheng07 with the default Zheng et al. (2007) parameters.

Functions

nc_galaxy_hod_zheng07_clear

If zheng07 is different from NULL, decreases its reference count and sets zheng07 to NULL.

Instance methods

nc_galaxy_hod_zheng07_free

nc_galaxy_hod_zheng07_ref

Increases the reference count of zheng07 by one.

Methods inherited from NcGalaxyHOD (7)
nc_galaxy_hod_free

Decreases the reference count of hod by one.

nc_galaxy_hod_gen

Draws an integer realization of the central and satellite occupations of a halo of mass $e^{\ln M}$. Satellites are drawn only when a central is present.

nc_galaxy_hod_get_stochastic_central

Gets whether the central galaxy is drawn stochastically.

nc_galaxy_hod_mean_n_central

Computes the mean central galaxy occupation of a halo of mass $e^{\ln M}$.

nc_galaxy_hod_mean_n_satellite

Computes the mean satellite galaxy occupation of a halo of mass $e^{\ln M}$.

nc_galaxy_hod_ref

Increases the reference count of hod by one.

nc_galaxy_hod_set_stochastic_central

Sets whether the central galaxy is drawn stochastically.
