Real part of the visibilities at 870 μm. Case 1: no planet embedded in the disk and t = 2 Myr. Case 2: a single planet embedded in the disk of 20 M_Jup mass at ~10 AU and t = 10 Myr. Case 3: two planets simultaneously interacting with the disk, 20 M_Jup at ~10 AU and 5 M_Jup at ~70 AU, and t = 10 Myr. Case 4: two planets in the disk, but the outer planet is injected t = 3 Myr after the inner planet, 20 M_Jup at ~10 AU and 15 M_Jup at ~70 AU, and t = 3.5 Myr. ALMA Cycle 0 is over-plotted for comparison.
