K-band (top) and H-band (bottom) MCFOST modeling of HD 100546. From left to right: NIR images (normalized intensity to one at maximum, in logarithmic scale), visibility (red solid lines) and closure phase (red crosses), compared with the interferometric observations (black circles and error bars). In the middle panels, the “kink” in the model visibility curves at B ~ 10 m is a real feature caused by the sharp inner edge of the outer disk.
