AGN component #62

Hi Adam, I was wondering how is it possible to include an AGN component into the fitting as in your nature paper? Is that included somewhere in BAGPIPES? Thanks so much!

Yes this is possible, here are the instructions for the AGN component as included in the paper. Note that this just includes a broken power law and broad Ha and Hb components, it's not a full AGN model.

agn_comp = {}
agn_comp["hanorm"] = (0., 25.*10**-18)
agn_comp["f5100A"] = (0., 10**-19)
agn_comp["sigma"] = (1000., 5000.)
agn_comp["sigma_prior"] = "log_10"

agn_comp["alphalam"] = (-2., 2.)
agn_comp["alphalam_prior"] = "Gaussian"
agn_comp["alphalam_prior_mu"] = -1.5
agn_comp["alphalam_prior_sigma"] = 0.5

agn_comp["betalam"] = (-2, 2.)
agn_comp["betalam_prior"] = "Gaussian"
agn_comp["betalam_prior_mu"] = 0.5
agn_comp["betalam_prior_sigma"] = 0.5

fit_instructions["agn"] = agn_comp
