Table 1: Summary of the AMBER $\eta$ Car observations using the UT2, UT3, and UT4 telescopes.
Table 2: Diameters obtained by fitting Hillier et al. (2001) model visibilities to the measured AMBER visibilities. Errors are $\pm$ 4% for the diameters in the continuum and $\pm$ $10\%$ in the lines (see text).
