VLTI/GRAVITY K-band interferometric visibilities of DoAr 44. Left: UV coverage of the observations in M λ. Right: squared visibility as a function of UV distance ( $\sqrt{u^{2} + v^{2}}$ $\$\sqrt{u^{2}+v^{2}}$$ ) in Mλ. We note that V² does not reach unity at the shortest baselines, indicating the presence of an extended component, whose angular size is larger than the maximum recoverable scale.
