Changing optical properties

It might be useful for some studies to deviate from the default values provided for optical material properties.

More information on the available properties can be found on the legendoptics documentation. Especially important is the functionality of the legendoptics.store which allows users to easily swap some of the default implementation with their own.

As an example, consider this simple file lar-ly.py that can be specified on the command line: legend-pygeom-l200 --pygeom-optics-plugin lar-ly.py:

from __future__ import annotations

import pint
from legendoptics.lar import lar_scintillation_params

u = pint.get_application_registry()
lar_scintillation_params.replace_implementation(
    lambda _: lar_scintillation_params.original_impl()(flat_top_yield=40 / u.keV)
)

This sets the flat-top light yield (as described in legendoptics.lar.lar_scintillation_params()) to 40 photons/keV.
