GRAVITY+UT HR observations of S CrA N on 2016 July 20. The Brγ line profile normalised to the continuum is shown in the top row. The radial velocity is with respect to the LSR. Dashed lines represent smoothed data by two spectral channels. Left: wavelength-dispersed visibility amplitudes measured in the UT3-UT4, UT2-UT4, and UT1-UT4 (middle row), and the UT2-UT3, UT1-UT3, and UT1-UT2 (bottom row) baselines. Middle: same as left, but for the wavelength-dispersed differential-phase signals. For clarity, the differential phases of the first and last baselines have been shifted by +10° and –10°. Right: wavelength-dispersed closure phase signals for the triplets UT2-UT3-UT4 and UT1-UT3-UT4 (middle row), and UT1-UT2-UT4 and UT1-UT2-UT3 (bottom row).
