Notes. The errors correspond to the 16th and 84th percentiles of the MCMC fit. A “_” indicates the fixed parameters.

^(*)

The reported σ is the half width at half maximum of a Lorentzian function in the functional form f(λ) = f_peakσ²/[(λ − λ_peak)² + σ²], where f_peak and λ_peak are the peak flux and centroid, respectively.
