SED fits from UV to hard X-rays of ESO 141-G55 using the RELAGN+REFLKERRD baseline model for the 2022 simultaneous XMM-Newton (pn: black; OM: magenta) and NuSTAR (blue) data, fixing the black hole spin to zero (left panels) and to 0.998 (right panels). The values of the best-fit parameters are reported in Table 6. Top panels: Data-to-model ratio. Bottom panels: 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 (dotted-dashed curves; hot corona), and relativistic reflection (three-dotted-dashed curves). For clarity, the weak narrow Gaussian line component is not displayed.
