Left panel: illustration of the model with a single SMBH in the center surrounded by a BLR (yellow) and the scattering region (gray) is shown. Right panel: profiles of polarization angle (top panel), the degree polarization (middle panel), and the total flux (bottom panel) when viewed from two intermediate inclinations. The polarization angle is given in degrees (°). We point out that the degree of polarization is given as fraction units and is lower than the ones we obtain in the following section due to the different size and optical depth of the scattering region. The total flux is given in arbitrary units. Model parameters are the same as the ones given by Savić et al. (2018).
