Notes. The columns provide a name for the line or doublet (Line), the rest-frame wavelength of the emission feature (λrest), the central wavelength of each line/doublet (λcentral) used as center for estimating the effective wavelength range the lines were searched for (Effective z-range), the width of the FELIS templates centered on the central wavelength (width), the Gaussian template line width (σGauss), the sampled flux ratios of the emission doublets (Flux ratio), and finally the total number of templates used for each line or line doublet (NTemplates). The widths of the two components of emission line doublets were required to be the same. The rest-frame wavelength sampling of each template was set to 0.05 Å per pixel. The sampling of the range of the Gaussian line widths and the doublet ratios are indicated with ‘Δ’.
