An emission line flux ratio appearing in the Abstract and under point 6 of the Summary in § 5 was inadvertently inverted.
In the Abstract the relevant sentence should state:
``The broad Hα/Hβ and Hβ/He I flux ratios and the Balmer emission-line responsivity are observed to decrease from the line center to the line wings.''
Under point 6 of the Summary in § 5 the relevant sentence should state:
``Because the emissivities and responsivities of the optical recombination lines are anticorrelated with the incident continuum flux, observations that Hα/Hβ and Hβ/He I flux ratios and the Balmer line responsivity decrease from the core to the wings indicate that the BLR velocity field diminishes with increasing distance from the central continuum source.''
This emission line flux ratio, Hβ/He I λ5876, is quoted in its correct form in § 3.6 and Figure 8, where it was discussed.
In addition, two sentences within § 3.3 should be clarified as follows.
About midway down paragraph 1, the sentence should read:
``After positing that the UV continuum is more intimately connected to the driving ionizing continuum and accounting for the relation that they found between the λ5100 and λ1350 continuum bands (F5100~F0.561350), the relation τ~F0.53UV resulted.''
The second sentence of paragraph 5 should state:
``As discussed in § 3.1, the low-state responsivity is higher in every case, and Figure 3 shows that the line's radial responsivity and Rη shift to larger distances in higher continuum states.''
Finally, we also note that the work cited in our paper as K. Horne (2004, in preparation) has been submitted and is anticipated to appear as Cackett, E. M., & Horne, K. (MNRAS, in press [2005]).
None of these changes affects the results of the paper.
