Nuclear spectra of COS1118 (Top) and COS590 (Bottom) used to produce the BLR template. Data and residuals are in black, total model is in dashed red, continuum is in orange, broad Balmer lines and FeII emission from the BLR are in dark and light green, respectively. FeII emission in these two targets is weak, and in COS590 almost marginal. Additional Gaussian emission line components are shown as dark to light purple and the total emission line model is shown as a dashed purple line. The gray shaded region marks the wavelength range that was excluded in the fitting process.
