Table 1: Squared visibilities of $\ell$ Car in the K band from VINCI. The stations of the new measurements are marked in bold characters. The calibrators are given in italic characters. The stated Julian date JD₀ is JD -2.452 10⁶. The azimuth is counted in degrees clockwise from North ( $N=0\deg$ , $E=90\deg$ ), and B is the projected baseline in meters. The pulsation phase $\phi$ is computed using the P and T₀ parameters from Szabados (1989).
Table 2: Continued from Table 1.
Table 3: Relevant parameters of the calibrators of $\ell$ Car (F6Ib-K0Ib), taken from Bordé et al. (2002).
Table 4: Journal of MIDI observations of $\ell$ Car on the UT2-UT3 baseline. JD₁ is defined as JD -2 453 104 (pulsation phase $\phi = 0.901$ ). B is the projected baseline length, Alt. the altitude of the star and PA is the position angle of the projected baseline ( $N=0^\circ$ , $E=90^\circ$ ).
Table 5: Best fit model parameters for the VINCI data in the K band. The adjusted model is the superimposition of a limb darkened disk representing the stellar photosphere and a Gaussian representing a CSE. $\theta _{\rm LD}$ is the LD angular diameter of the star, $D_{\rm CSE~K}$ is the FWHM of the Gaussian (in mas), and $I_{\rm CSE~K}$ is the ratio of the CSE brightness to the stellar brightness in the K band.
Table 6: Fraction of polarized flux (p) for bright Cepheids. This list is limited to Cepheids brighter than m_V = 6.0 at maximum present in the catalogue assembled by Heiles (2000), apart from RS Pup. The color excess E(B-V) reported by Fernie (1990) is given for each star, and the p values larger than 1% are marked in bold characters.
