XMM-Newton pn (black), MOS1 (red), and MOS2 (green) 0.3–7 keV spectra and best-fit models (stepped continuous thick lines) for the ten detected HYPERION QSOs presented in this paper. Spectra were further rebinned for visual purposes and are reported at their rest-frame energy. Residuals are shown as data minus best-fit model in the bottom panels. For the source J1342, blue, cyan, and magenta represent the second data set.
