We present high-resolution HST images of all 35 AGNs with optical reverberation-mapping results , which we have modeled to create a nucleus-free image of each AGN host galaxy . From the nucleus-free images , we determine the host-galaxy contribution to ground-based spectroscopic luminosity measurements at \lambda 5100 Å . After correcting the luminosities of the AGNs for the contribution from starlight , we re-examine the H \beta R _ { BLR } – L relationship . Our best fit for the relationship gives a powerlaw slope of 0.52 with a range of 0.45 - 0.59 allowed by the uncertainties . This is consistent with our previous findings , and thus still consistent with the naive assumption that all AGNs are simply luminosity-scaled versions of each other . We discuss various consistency checks relating to the galaxy modeling and starlight contributions , as well as possible systematic errors in the current set of reverberation measurements from which we determine the form of the R _ { BLR } – L relationship .
