Light curve of KMT-2021-BLG-1122 constructed with the combined data obtained from the three KMTNet telescopes (KMTA, KMTC, and KMTS). The curve drawn over the data points is the best-fit model found under the 2L1S interpretation. The lower panel displays the whole view, and the upper panel shows the enlarged view of the anomaly region. The epochs marked by t₁, t₂, and t₃ indicate the three major anomaly features.
