Left: average optical depth ⟨τ⟩ (considering all deflector types) as a function of cosmological matter density parameter Ωm, modeling the deflectors with the SIS and SIE models. Right: normalized redshift distributions ωzs and ωzd of the lensed sources and of the deflectors (for the early-type galaxy population) for different values of Ωm = 0,0.3 and 1. All simulations were produced for θmin = 0.2′′.
