Zoom-in view of the light curve near the peak. The vertical dashed lines denote the four regions of deviations: 9311.35 ≤ HJD′ ≤ 9312.42 (R₁ region), 9312.42 ≤ HJD′ ≤ 9312.70 (R₂ region), 9312.70 ≤ HJD′ ≤ 9313.00 (R₃ region), and 9313.00 ≤ HJD′ ≤ 9312.48 (R₄ region). The curves over the data represent the 2L2S (close), 3L1S (close–wide), 2L1S (wide), and 1L1S models, for which the residuals are shown in the lower panels. The 2L1S model is found by modeling the data excluding those in the R₃ region.
