Distribution of the time delay between the first and second arriving images (Δt₁₂) for mock lensed systems. The left panel shows the cumulative distribution, i.e., the number of systems with Δt₁₂ smaller than a threshold Δt_th, plotted along the x-axis. The filled cyan histogram represents the full test sample of 5,811 systems. Blue, green, purple, and red curves correspond to the distributions after the 1st, 3rd, 7th, and 14th observations, respectively. For these curves, solid and dashed line-styles indicate the subsets with scores 𝒫 > 0.75 and 𝒫 > 0.99. The right panel presents the Δt₁₂ distributions for lensed systems with scores below those thresholds, i.e., with 𝒫 < 0.75 and 𝒫 < 0.99, using solid and dashed curves, respectively. The y-axis gives the fraction of such systems in each Δt₁₂ bin as a percentage. Purple and red curves again correspond to results after the 7th and 14th observations.
