Top left: best-fit H-band V² from the radiative transfer (red diamonds) and PIONIER V². Top right: same for the PIONIER closure phases that were only used to check for consistency (B_max is the longest baseline of the triplet). Bottom left: best-fit K-band V² from the radiative transfer (red line) and AMBER V² (black). Bottom right: same for the modeled N-band visibilities and the MIDI data (detailed in Matter et al. 2014).
