Aperture synthesis images of V766 Cen at 1.58/ 1.59 μm (left), 1.68 μm (middle), and 1.77 μm (right). The three rows represent the three epochs. Contours are drawn at levels of 90%, 70%, 50%, 30%, 10%, 3% of the peak intensity. The peak intensity is normalized to unity for each image separately. The dotted circles indicate our estimated Rosseland angular diameter. The dashed circles in the lower left corners indicate the sizes of the array angular resolution λ/ 2B_max.
