L_{2 − 10  keV} vs. L_6 μm relation for QSOs with L_bol > 10⁴⁷ erg s⁻¹. The filled and empty red stars represent W0410−09 for the BORUS and MYTORUS models, respectively. The Hot DOGs are represented with stars of different colors, as in Fig. 6. The gray points and red dots represent the X-WISSH hyperluminous Type I QSO sample (Martocchia et al. 2017) and two reddened QSOs (Martocchia et al. 2017). We also report X-ray-to-MIR relations derived for different optical, MIR, and X-ray selected AGN samples (Fiore et al. 2009; Lanzuisi et al. 2009; Stern 2015; Chen et al. 2017).
