Corner plot for source ID 00039, best fit with a double power law soft excess. Here, the first instance of log(nH) is the host galaxy absorber column density (in units of ×10²² cm⁻²), log(norm) is the power law normalisation, log(factor) is the relative normalisation of the soft power law with respect to the hard power law, the first instance of PhoIndex is the photon index of the hard power law, the second instance of PhoIndex is the photon index of the soft power law, and norm is the relative renormalisation of the background model with respect to the source model, which is in agreement with 1.
