Description [src]
final class NumCosmo.MultiplicityFuncDespali : NumCosmo.MultiplicityFunc
{
/* No available fields */
}Dark matter halo — Despali multiplicity function.
Reference: arxiv:1507.05627v2.
Constructors
nc_multiplicity_func_despali_new_full
Creates a new NcMultiplicityFuncDespali with the specified mass definition and Delta parameter.
Functions
nc_multiplicity_func_despali_clear
Atomically decrements the reference count of md by one. If the reference count drops to 0,
all memory allocated by md is released. Set the pointer to NULL;.
Instance methods
nc_multiplicity_func_despali_delta_c
Calculates the critical density using Kitayama & Suto 1996 interpolation (https://arxiv.org/pdf/astro-ph/9604141).
nc_multiplicity_func_despali_delta_vir
Calculates the virial delta using Bryan and Norman 1998 interpolation (https://arxiv.org/pdf/astro-ph/9710107).
nc_multiplicity_func_despali_free
Atomically decrements the reference count of md by one. If the reference count drops to 0,
all memory allocated by md is released.
Methods inherited from NcMultiplicityFunc (11)
nc_multiplicity_func_correction_factor
Computes the correction factor for the multiplicity function. Some multiplicity functions require mass-dependent corrections.
nc_multiplicity_func_eval
Evaluates the multiplicity function $f(\sigma, z)$ at the given
variance sigma and redshift z. The filter radius lnR identifies the
scale at which sigma was evaluated; non-universal models use it to query
further properties of the filtered power spectrum, such as the slope
$\mathrm{d}\ln\sigma_R/\mathrm{d}\ln R$. Universal models ignore it.
nc_multiplicity_func_free
Atomically decrements the reference count of mulf by one. If the reference count drops to 0,
all memory allocated by mulf is released.
nc_multiplicity_func_get_Delta
Gets the Delta Value.
nc_multiplicity_func_get_matter_Delta
Gets the Delta Value with the matter density definition.
nc_multiplicity_func_get_mdef
Gets the mass definition.
nc_multiplicity_func_has_correction_factor
Checks if the multiplicity function has a correction factor, e.g., NcMultiplicityFuncBocquet (when using matter density).
nc_multiplicity_func_peek_psf
Gets the filtered power spectrum, or NULL when none was set.
nc_multiplicity_func_set_Delta
Sets the Delta for mean or matter mass definition to mdef.
nc_multiplicity_func_set_mdef
Sets the mass definition to mdef.
nc_multiplicity_func_set_psf
Sets the filtered power spectrum used by non-universal multiplicity functions.
It must be the same filter that provides the sigma passed to
nc_multiplicity_func_eval(), otherwise the two are evaluated on inconsistent
power spectra.
Properties
Properties inherited from NcMultiplicityFunc (3)
NumCosmo.MultiplicityFunc:Delta
NumCosmo.MultiplicityFunc:mass-def
It refers to the halo finder used to obtain the multiplicity function (e.g., SO and FoF), and
the background density $\rho_\mathrm{bg}$ used in the mass definition \eqref{eq:mrr}.
See the enumerator NcMultiplicityFuncMassDef for more details about the
background density definition.
NumCosmo.MultiplicityFunc:powerspectrum-filtered
The filtered power spectrum used to obtain quantities beyond $\sigma_R$ itself, such as the slope $\mathrm{d}\ln\sigma_R/\mathrm{d}\ln R$ required by non-universal multiplicity functions. Universal models leave it unset.
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
