Modeled image of HE0230−2130. Plotted are the 1σ and 2σ contours of the predicted positions of the unobserved image E in the PL1 + PL2 (red), the PL1+cPL2+γext (green), and the PL1+PL2+rNIS (blue) model class. These predicted fifth quasar images would be above the detection threshold, but are not observed in the imaging data.
