Constraints on the luminosity of the accretion disk and host galaxy for all blazars in the sample (masquerading BL Lacs in red, true BL Lacs in blue, and undetermined in gray). Left: accretion disk luminosity constraints. The vertical line markers show the estimate derived in Section 2.1 and the horizontal line their respective uncertainties. In the case of true BL Lacs, as well as four of the blazars of undetermined nature, only upper limits are available. In the cases where there is no vertical line marker, Papers II and III either report no value of the bolometric luminosity or only an upper limit. The circles show the final value adopted, based on an additional comparison with the optical SED, as discussed in Section 2.1. We can see that the two estimates only disagree for three objects: VOU J150720−370902, 3HSP J152835.7+20042, and 5BZU J0158+0101. Right: estimated host galaxy luminosity following the procedure explained in Section 2.2. The estimates marked with a square result from optical spectrography, as reported in Paper III (see Appendix C for further details).
