Broadband SED models for the high- (left) and low-brightness states (right) of 3C 371. The top panels contain the broadband SEDs, with the contribution of each component and the best-fit model being represented with different markers, lines, and colours, as indicated in the legend. The bottom panels represent the residuals of the fitted models. We note that the EC scattering contribution via low-energy photons from the BLR was also considered. However, it is even fainter than that from the DT, and therefore does not fall within the scale of the figures and is not included.
