- class halotools.empirical_models.PreservingNgalHeavisideAssembias(**kwargs)¶
No positional arguments accepted; all argument are strictly keyword arguments.
Name of the method in the primary class whose behavior is being decorated
lower bound on the method being decorated with assembly bias
upper bound on the method being decorated with assembly bias
- sec_haloprop_keystring, optional
String giving the column name of the secondary halo property governing the assembly bias. Must be a key in the table passed to the methods of
HeavisideAssembiasComponent. Default value is specified in the
- splitfloat or list, optional
Fraction or list of fractions between 0 and 1 defining how we split halos into two groupings based on their conditional secondary percentiles. Default is 0.5 for a constant 50/50 split.
- split_abscissalist, optional
Values of the primary halo property at which the halos are split as described above in the
loginterpis set to True (the default behavior), the interpolation will be done in the logarithm of the primary halo property. Default is to assume a constant 50/50 split.
- splitting_modelobject, optional
Model instance with a method called
splitting_method_nameused to split the input halos into two types.
- splitting_method_namestring, optional
Name of method bound to
splitting_modelused to split the input halos into two types.
- halo_type_tupletuple, optional
Tuple providing the information about how elements of the input
tablehave been pre-divided into types. The first tuple entry must be a string giving the column name of the input
tablethat provides the halo-typing. The second entry gives the value that will be stored in this column for halos that are above the percentile split, the third entry gives the value for halos below the split.
If provided, you must ensure that the splitting of the
tablewas self-consistently performed with the input
- assembias_strengthfloat or list, optional
Fraction or sequence of fractions between -1 and 1 defining the assembly bias correlation strength. Default is 0.5.
- assembias_strength_abscissalist, optional
Values of the primary halo property at which the assembly bias strength is specified. Default is to assume a constant strength of 0.5. If passing a list, the strength will interpreted at the input
assembias_strength_abscissa. Default is to assume a constant strength of 0.5.
- loginterpbool, optional
If set to True, the interpolation will be done in the logarithm of the primary halo property, rather than linearly. Default is True.
