Spectrally resolved attenuation curve for FCC 167 (red line, this work) and for NGC 5626 (green line, Viaene et al. 2017a). Three reference curves are plotted: The Calzetti et al. (2000) and Battisti et al. (2017) average attenuation curves for different samples of galaxies (blue solid and dashed line, respectively) and the THEMIS extinction curve (black dotted line). All curves are normalised to the V -band central wavelength; A_V = 0.35 for FCC 167. For reference, the emission spectrum of the dust lane area is shown in the bottom panel. Several important emission lines (shaded green) and the NaD absorption line (shaded purple) are highlighted as well.
