Example Gaussian + linear-baseline fits to six prominent emission lines used to estimate centroids and deconvolved widths. We annotate the fitted centroid λc and the corresponding apparent velocity offset vγ = c(λc/λ0 − 1) in each panel; the annotated vFWHM values are derived from deconvolved widths (see Section 3.5).
