PMOIRED geometrical model fit to the Brγ region of GRAVITY data taken on RJD 60139. The upper left panel shows the (u, v) coverage, the lower left panel the normalized Brγ line profile (NFLUX), and the remaining panels the interferometric observables’ closure phase (T3PHI), differential phase (DPHI), and the absolute visibility (|V|). The data (black with gray error bars) are overplotted along with the model fit (red). The blue dots in the NFLUX and DPHI panels represent the continuum region used for normalization. The baselines and telescope triangles are given in the corner of each panel, and their colors correspond to the (u, v) coverage panel.
