SED of the source in Complex A (calculated in the rest frame of the source at z = 1.142). Black dots represent radio (VLA A-configuration), infrared (WISE), optical (SDSS), and γ-ray (Fermi) observations. Gray arrows indicate upper limits. Dashed red, and dotted-dashed green lines are the SED derived by Ghisellini et al. (2017) for the Fermi-detected FSRQ and BL Lac objects, respectively, in the luminosity bin of 10⁴⁰ − 10⁴¹ W. Solid blue line is obtained via fitting the synchrotron peak and keeping the inverse Compton peak at the frequency derived by Ghisellini et al. (2017; for further details see text).
