SED fit from UV to hard X-rays of 1H 0419-577 using the RELAGN+REFLKERRD model for the May (black) and November (blue) 2018 simultaneous XMM-Newton and NuSTAR. The values of the best-fit parameters are reported in Table 5. Top panel: Data-to-model ratio. Bottom panel: Intrinsic SED corrected for reddening and Galactic absorption (solid curves), with the main individual emission components: Outer disc (dotted curves), warm optically thick Comptonisation (dashed curves; warm corona), hot optically thin Comptonisation (dash-dotted curves; hot corona), and relativistic reflection (three-dotted-dashed curves). For clarity, the weak narrow Gaussian linecomponent is not displayed.
