Science functionality - colours from stellar Source objects

[AstarVienna]

Wish from the slack channel:
can I directly extract what the colours should be from the source object? I.e. without initiating the OpticalTrain() ?

Yes. If it uses a speXtra template (can be done with synphot spectra too, with more steps)

e.g.

from scopesim_templates.stellar import star

src = star(filter_name="Ks", amplitude=20, spec_type="a0v", library="pickles")
sp = src.spectra[0]

B = sp.get_magnitude(filter_curve="B", system_name="AB")
V = sp.get_magnitude(filter_curve="V", system_name="AB")

print("B-V color = ", B - V)

Awesome! Could you write this in a ipynb and add it to the scopesim_templates docs folder, please? Thanks! Am Di., 12. Apr. 2022 um 11:46 Uhr schrieb Miguel Verdugo < ***@***.***>:
