Comparison of fluxes computed by CIGALE (Flux_prism) with Gaussian fitting of the lines observed in the grating configuration (Flux_grating) for objects observed in both configurations. The points corresponding to each emission line are colour-coded to better identify each species (see inside caption). The diagonal line shows the 1-to-1 relation (Flux_prism = Flux_grating), while the dashed lines present offsets (Flux_prism = 0.5 Flux_grating) and (flux_prism = 2.0 Flux_grating). The horizontal and vertical dashed lines show the level of the 3σ background around the [NII] + Hα lines.
