Examination of the consistency of our results with spectroscopic identification case by case using a sample taken from Massaro et al. (2016). The x-axis indicates the source number only, and the vertical dashed line separates the BL Lacs and FSRQs that are optically identified by Massaro et al. (2016, and references therein). ﹩{\rho }_{{\rm{s}}}^{a}﹩, ﹩{\rho }_{{\rm{s}}}^{b}﹩, and ﹩{\rho }_{{\rm{s}}}^{c}﹩ shown on the Y-axis for each panel are for the radio, X-ray, and optically selected sources, respectively. The pink (BL Lac-like) and gray (FSRQ-like) regions mark the type evaluations with our method with ﹩\sigma \gt 90 \% ﹩.
