L6 μm vs. L2−10 relation. The red circle represents W1835 for the MYTORUS geometry (both in X-ray and SED analysis) with the range of systematic uncertainty due to different modelings (see Tables 1 and 3) reported as the gray shaded region. Blue triangles report a compilation of hot DOGs in Ricci et al. (2017a) except for W1835, which we update here. Magenta squares report W0116+0505 with L6 μm reported by Vito et al. (2018; empty square) or estimated by our SED fitting (filled square; see Sect. 5.1). Black stars and green triangles represent the X-WISSH hyperluminous type I quasar sample (Martocchia et al. 2017) and two reddened quasars (Martocchia et al. 2017). The orange diamond reports the best-fit L2−10 value obtained from X-ray spectral analysis performed on a stacked X-ray spectrum of a sample of ERQ sources observed in Chandra in Goulding et al. (2018). In the latter, the error bar represents the range of L6 μm in the sample. We also report X-ray-to-MIR relations derived for different optical/MIR/X-ray selected AGN samples.
