Distribution of the largest time delay (Δt_max) and the corresponding magnification ratio in all the unresolved systems is shown in the left panel; the lighter and darker shades of blue show the 68 and 95% credible regions, respectively. The middle panel presents the 1D marginalised distribution of the magnification ratio. The right panel shows the cumulative distribution of Δt_max, i.e. indicating the number of systems (in one cumulative year) that have Δt_max higher than a given value – resolved (orange) vs. unresolved (blue). It is evident that unresolved systems typically exhibit low time delays, with a median value of Δt_max of ~2.03 days and approximately 10% having values above 10 days.
