imf_type: str (default “bi”)

Initial Mass Function (IMF) parametrization. Options are:

• un (unimodal)

• bi (bimodal)

• ku (Kroupa universal)

Methods Documentation

__call__(theta)

Call self as a function.

constrain_duplicates()

Constrain the parameters with the same name to have the same value during calling.

fix(fixed_vals)

Fix a set of parameters in parnames using a dictionary.

get_filename(MH, age, alphaFe='base', imfslope=1.3)

Retrieves the filename containing the spectrum of given ages, metallicities, alpha/Fe and IMF slope.

Parameters

MH: float

Metallicity of the SSP.

age: float

Age of the SSP.

alphaFe: float or string

Alpha-element abundances. Defaults to “base” models. For BasTI isochrones, models can have alpha element abundances of 0 and +0.4.

imfslope: float

Slope of the IMF. Defaults to 1.3.

gradient(theta)

plot(theta, ax=None, plottype=None, **kwargs)

Plot the model for a given set of parameters.
