Fig. A.1
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. |
| Open with DEXTER | |

Fig. A.2
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. |
| Open with DEXTER | |

Fig. A.3
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. |
