GRAVITY observations of DoAr 44 on June, 22. Left: (u, v) spatial frequency plane corresponding to the six projected baselines during the 3.7 h of observations. Middle: continuum squared visibilities as a function of baseline, recorded in the central spectral channel of the fringe tracker (λ = 2.15 μm). The gray circles at the bottom of the panel correspond to the residuals after the best fit model has been subtracted (see text). Right: closure phases measured in the central spectral channel as a function of baseline. The error bars amount to 2% on the squared visibilities and 0.3° on the closure phases (see text for details).
