\caption{\textbf{(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 JD$_0$ 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.
