DispersionConst

class dysmalpy.models.DispersionConst(sigma0=10.0, **kwargs)

Bases: DispersionProfile

Model for a constant dispersion

Parameters:

• sigma0 (float) – Value of the dispersion at all radii

• tracer (string) – (Attribute): Name of the dynamical tracer

Attributes Summary

param_names	Names of the parameters that describe models of this type.
sigma0

Methods Summary

evaluate(r, sigma0)

Dispersion as a function of radius

Attributes Documentation

param_names = ('sigma0',)

Names of the parameters that describe models of this type.

The parameters in this tuple are in the same order they should be passed in when initializing a model of a specific type. Some types of models, such as polynomial models, have a different number of parameters depending on some other property of the model, such as the degree.

When defining a custom model class the value of this attribute is automatically set by the Parameter attributes defined in the class body.
