Left: observed (black) normalized flux, squared visibility amplitudes, UD diameters predicted form our data (blue) and from the best-fit PHOENIX model (red), and closure phases in degree (from top to bottom) of AH Sco obtained with the MR-K 2.1 μm setting. Right: same as left but obtained with the MR-K 2.3 μm setting. The blue curves show the best-fit UD model, and the red curves the best-fit PHOENIX model prediction. For the baseline lengths and position angles, see Table 1. In the 2nd panel on the left, two model lines overlap, corresponding to baselines of 40.6 m and 40.4 m.
