Correlation between the luminosity of the broad Hα emission line and the starlight-corrected AGN continuum luminosity at 5100 Å. Only AGNs with host-galaxy starlight removal from the measured continuum based on HST high-resolution imaging are shown (Bentz et al. 2013), i.e. the AGNs listed in Table 1. The solid line represents the best fit to Eq. (2), with parameters given in line 1 of Table 1. The short-dash lines show the ±1σ envelope, and the long-dash lines show the ±2.6σ (99% confidence level) envelope.
