[OIII] (top) and Hβ (bottom) emission line stacks (black) and total fits (red). The individual Gaussian components which comprise the total fit are shown in different colours, with the same components shown in the same colours in both fits. The individual components of the Hβ fit are constrained to have the same width and velocity as those obtained from the [OIII] fit, thereby demonstrating that no additional broad component is required to account for light scattered from the BLR. The residuals are shown underneath each fit.
