## 1. Erratum

We found a bug in the formula used to calculate the uncertainties in the virial products. This error produced incorrect uncertainties for the virial products and consequently the black hole mass ($M_{BH}$) measurements reported in Tables 4 and 5. These uncertainties were used to produce Figures 12, 13, and 14. This error is minor and does not affect any of our results or their interpretation, and thus no edits to the text are necessary. We here provide updated/corrected tables and figures produced with the correct $M_{BH}$ uncertainties.

Notes.

<footnote>a Measurements are in the quasar rest frame. If the lag is detected by JAVELIN, we use the JAVELIN-reported lag by default; otherwise, we use the CREAM-reported lag.</footnote>

<footnote>b Line widths are measured using Prepspec. The mean line widths are measured from the broad component only, and the rms line widths do not include the continuum.</footnote>

<footnote>c Virial products were converted to $M_{BH}$ using $f = 4.47$, as measured by Woo et al. (2015).</footnote>

<figure><img src="image_3.png" /><figcaption>**Figure 12.** Comparison of $M_{BH,SE}$ measurements from Shen et al. (2015) and our new measurements ($M_{BH,RM}$). As in Figure 11, we show previous measurements in blue (Bentz & Katz 2015) and green (Du et al. 2016). The dotted red line indicates a ratio of one-to-one. Most of our quasars have consistent masses between the two methods, with some deviation for both SDSS-RM and the Du et al. (2016) sample at low RM masses.</figcaption></figure>
