Correlations of L_Hα − (bottom panel) and L(Hβ) − L(5100 Å) (bottom). The solid lines represent the Greene & Ho (2005) correlations obtained from a sample of type 1 AGN with low galaxy contribution in the optical continuum emission. A significant displacement from such relations is found for our low-luminosity AGN subsample, in which the continuum emission at 5100 Å is dominated by host galaxy emission.
