Distribution of the resolving power log(δi/σi) at z = 0.55 for Dn4000, Hδ, and Mgwide, respectively. Red histograms correspond to S/NI, obs = 10, while blue histograms stand for S/NI, obs = 30. The red dotted line separates the region where log(δi/σi) < 0 (in gray) from the one where log(δi/σi) > 0 (in white).
