Light curve of MOA-2012-BLG-006 = OGLE-2012-BLG-0022. OGLE and MOA data are marked using black and red points, respectively. Panel a) presents the 2012 light curve with both subevents. Panel b) shows the model residuals. Panel c) gives zoom-in on the anomaly. Panel d) presents the source trajectory (black line) relative to the planetary caustic (blue curve), which is at the origin of the coordinate system. The host star is located at (θ_x/θ_E,θ_y/θ_E) = (4.17,0.0). Source positions from one OGLE night and two MOA nights are marked and are aligned with photometry shown in panel c). The circles have a radius of ρ.
