All Tables

Table 1: VLTI-VINCI observations of Altair performed in the H and K bands.
Table 2: Relevant parameters of the calibrators used for VINCI observations of Altair.
Table 3: Input and derived parameters obtained from a $\chi ^2$ minimization procedure applied to several data sets: all data (BMAD), near-IR V² and closure phases (BMIRCP), closure phases alone (BMCP), and near-IR V²alone (BMIR). There is no uncertainty associated to $\beta$ and $T_{\rm p}$ because they define two test models based on theoretical limits for the gravity darkening (see text for details). Selected dependent parameters for the best models are also listed.
Table 4: Apparent and absolute magnitudes of Altair, using the Hipparcos parallax ( $\pi = 194.45 \pm 0.94$ mas).
