Squared visibility |V²| (shifted by dataset number) for different baselines B/λ (in cycles). The CHARA/MIRC observations are at the bottom, NPOI in the middle, and CHARA/VEGA at the top (blue); synthetic data for the joint model are plotted for comparison (yellow). Overall trends (|V²|(B/λ)) seem to be correctly described, although there are some systematics for small groups of data.
