Link to the official sites of the SSP models currently used in PST:

• (Py)PopStar

  See Mollá et al 2009 and Millán-Irigoyen et al 2021 for details. To increase the read speed, these models are converted into FITS files. See instructions for ingesting the models in the PST format.

• Granada-MILES

• XSL

• Bruzual & Charlot 2003

  See instructions for ingesting the models in the PST format.

Ingesting new SSP models is a straightforward exercise. Users only need to create a new SSP model class by inheriting from the base class SSPBase:

from pst.SSP import SSPBase

class MyNewSSPModel(SSPBase):
    def __init__(self, *args, **kwargs):
        # Do some stuff to initialise the main SSP properies
        self.initialise_model()

    def initialise_model(self):
        self.metallicities = ...
        self.ages = ...
        self.L_lambda = ...

The SSP model must always include these three properties for it work.
