Overall spectrum of PKS 1510-089. The short-dashed blue line represents the synchrotron component, the dashed red line is the inverse Compton (IC) component with seed photons originating from the dusty torus (DT) before absorption, and the dashed-dotted violet line is the IC radiation with seed photons originating from the broadband region (BLR). The dash-double-dotted orange line is the SSC component. The solid black line represents the sum of all the components, corrected for EBL absorption (see text for details) and absorption on the low-energy photons originating from the BLR and the DT.
