Location of J0100+2802 (red stars) in the X-ray-to-optical power-law slope parameter ﹩{\alpha }_{\mathrm{ox}}﹩ vs. 2500 Å monochromatic luminosity. The gray dots are the quasars from the samples of Just et al. (2007), Steffen et al. (2006), and Gibson et al. (2008). The blue dots are the weak line quasars and PHL 1811 analogs from Luo et al. (2015). The solid line represents the Just et al. (2007) ﹩{\alpha }_{\mathrm{ox}}\mbox{--}{L}_{2500\mathring{\rm A} }﹩ relation, and the dashed line marks the division between X-ray weak and X-ray normal quasars adopted in Luo et al. (2015). For J0100+2802 the two red stars represent the values of ﹩{\alpha }_{\mathrm{ox}}﹩ derived with X-ray photon indices of 3.03 and 2.0, respectively.
