Zoom-in view around the peak of the light curve. The lower five panels show the residuals of the tested models under 3L1S, 2L2S, 2L1S, 1L2S, and 1L1S interpretations. The curve drawn in each residual panel is the difference from the 3L1S model. The curves of the 1L1S, 2L1S, and 3L1S models are drawn over the data points of the light curve in the top panel. The epochs marked t_1; t₂, and t₃ indicate the times of the major anomalous features.
