Tinker13Cens¶
- class halotools.empirical_models.Tinker13Cens(threshold=10.5, prim_haloprop_key='halo_mvir', redshift=0.0, **kwargs)[source]¶
Bases:
OccupationComponent
HOD-style model for a central galaxy occupation that derives from two distinct active/quiescent stellar-to-halo-mass relations.
Note
The
Tinker13Cens
model is part of thetinker13
prebuilt composite HOD-style model. For a tutorial on thetinker13
composite model, see Tinker et al. (2013) Composite Model.- Parameters:
- thresholdfloat, optional
Stellar mass threshold of the mock galaxy sample in h=1 solar mass units. Default value is specified in the
model_defaults
module.- prim_haloprop_keystring, optional
String giving the column name of the primary halo property governing the occupation statistics of gal_type galaxies. Default value is specified in the
model_defaults
module.- redshiftfloat, optional
Redshift of the stellar-to-halo-mass relation. Default is set in
sim_defaults
.- quiescent_fraction_abscissaarray, optional
Values of the primary halo property at which the quiescent fraction is specified. Default is [10**12, 10**13.5, 10**15].
- quiescent_fraction_ordinatesarray, optional
Values of the quiescent fraction when evaluated at the input abscissa. Default is [0.25, 0.7, 0.95]
