Near-IR spectra of the sample QSOs centered on the Hα emission line, along with our double-Gaussian fits to the line profile. The two Gaussians represent an intermediate-width component (corresponding to the ILR), and a very broad component (corresponding to the VBLR; see text). For each QSO the upper panel shows the normalized QSO spectrum (black) along with the double-Gaussian fit (grey); the lower panel shows the residual spectrum after subtraction of the double-Gaussian fit. The zero velocity is based on the central wavelength of the intermediate-width component of the double-Gaussian fit (see Table 2). The ticks below each QSO name indicate the expected locations of the [N ii] doublet.
