N2 - We present high-resolution Hubble Space Telescope images of all 35
active galactic nuclei (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 5100 Å. After correcting the luminosities of the
AGNs for the contribution from starlight, we re-examine the Hß R
BLR-L relationship. Our best fit for the relationship gives a
power-law 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.
