Observed spectral visibilities against spatial frequencies measured in the K band (left) and the H band (right). Each night/dataset is indicated with a specific color.

Observed spectral visibilities against effective spatial frequencies measured in the K band (left) and the H band (right) and assuming i = 48° and PA = 135°. Each night/dataset is indicated with a specific color.

Observed spectral closure phases (in degrees) against maximum spatial frequencies measured in the K band (upper panels) and the H band (lower panels). Each night/dataset is indicated with a specific color, according to the same color code as in Fig. A.1.
