Table 1: Throughput measured at $1.55~\mu$ m (laser source) for unpolarized light of the integrated optics combiner before and after connecting performed by the GeeO company. The "-'' denotes that measurements have not been done.
Table 2: List of the targets observed at Paranal during July 2002 with IONIC and VINCI on the VLTI. The stellar angular diameters are extracted from the CHARM database (Richichi & Percheron 2002).
Table 3: Average flux ratio on $\alpha$ Aql. $\kappa$ is estimated with the ON-SOURCE acquisition (fluctuation fitting) and $\kappa '$ with the BEAM-A/BEAM-B acquisitions. See Sect. 3.2.1 for a global explanation of both methods and see Table 1 for laboratory data.
Table 4: Instrumental visibility with the IONIC component. We assume that stars are uniform disks and we take an effective wavelength of $1.63~\mu$ m. The angular diameters come from the CHARM database. This table summarizes the values of Fig. 5.
Table 5: Angular diameters estimated from the IONIC measurements. We assume an instrumental visibility of $87\%$ and an effective wavelength of $1.63~\mu$ m. The previous measurements are taken from the CHARM database. LBI is for Long Baseline Interferometry and SPE for SPectroscopic Estimation.
