Table 1: Relevant parameters of the calibrators used for VINCI observations of Achernar (continued in Table 2).
Table 2: Relevant parameters of the calibrators used for VINCI observations of Achernar (continued from Table 1). The references are the same as in Table 1.
Table 3: (a) Squared visibilities of Achernar in the K band from VINCI, ordered by increasing azimuth angle of the projected baseline. The calibrators are named using their HR number, when no Bayer designation is available. The stated Julian date JD₀ is JD $-~2.452\times10^6$ . The azimuth is counted in degrees clockwise from North ( $N=0\deg$ , $E=90\deg$ ), and B is the projected baseline in meters. The squared visibilities are followed in subscript by the statistical and calibration uncertainties.
Table 3: (b) Squared visibilities of Achernar in the K band from VINCI (continued from Table 3a).
Table 3: (c) Squared visibilities of Achernar in the K band from VINCI (continued from Table 3b).
Table 3: (d) Squared visibilitiess of Achernar in the H band from VINCI, equipped with the IONIC integrated optics beam combiner.
Table 4: Best fit parameters (and corresponding uncertainties) of our simple model consisting in a Gaussian elliptical envelope superimposed on a uniform ellipse representing the central star. The fit was computed on our complete H and K band data set.
