SED calculated with the model described in the text. The colors indicate the following: model A (red), B (blue), C (light blue), D (green), and E (violet). The dash-dotted light green line shows the contribution from the accretion disk. We also report the contribution from the synchrotron (dotted), SSC (long-dashed), and EC (short-dashed). The vertical orange lines show the COSI energy band. For reference, in gray we also show the observational data points of the FSRQ 0836+710 (z = 2.1) from ASI-SSDC.
