Examples of emission line fits. The rest-frame spectrum of J1440+53 and residuals are shown in black, and the fit model is in red. Narrow (n), intermediate (i), and broad (b) components are shown in green, blue, and magenta. The spectra were smoothed using a 4-pixel boxcar, and residuals were scaled up from zero to reduce blank space. Vertical dotted lines correspond to the peak of the narrow component fit to each line.
