Figure 2
VLTI/AMBER and VLT/CRIRES observations of CO bandhead emission of HD 327083 [61]. (a): Observed flux spectrum (black) and model fit (red) based on a Keplerian disk. (b): Differential phase spectrum (histogram) with the Keplerian model prediction at a spectral resolution of VLT/CRIRES (blue) and of VLTI/AMBER (red).
