Peak synchrotron frequency in the rest frame (﹩{\nu }_{\mathrm{sy}}^{\mathrm{pk}}﹩) vs. the peak synchrotron luminosity (L_sy^pk). The magenta stars represent the two new sources found in the present work. These are consistent with the other high-z BL Lacs using the photometric method, which displays the high luminosity and high-synchrotron peak behavior. We show six new BL Lacs from Rau et al. (2012, cyan diamonds), five BL Lacs from Kaur et al. (2017, yellow squares), and all the FSRQs and BL Lacs from the 3LAC catalog with known redshifts (red and blue circles, respectively). The separation of the LSP, ISP, and HSP regions are also plotted (dotted lines).
