$\begin{figure} \par\includegraphics[width=8cm,clip]{3603fig1.eps} \end{figure}$ Figure 1: Limb darkened disk angular diameter of $\ell$ Car deduced from VINCI observations on the B3-M0 siderostat baseline (filled squares) and the UT1-UT3 baseline (open squares). The solid curve is the best-fit model from Paper I, using the siderostat data only.

$\begin{figure} \par\includegraphics[width=8cm,clip]{3603fig2.eps} \end{figure}$ Figure 2: Absolutely calibrated MIDI (thick curve) and IRAS LRS spectra (thin solid and dotted curves) of $\ell$ Car, using HR 3187 as a spectrophotometric standard star. The theoretical spectrum of a blackbody with T = 5500 K and an angular diameter of 2.70 mas is superimposed for reference (solid curve).

$\begin{figure} \par\includegraphics[width=8cm,clip]{3603fig3.eps} \end{figure}$ Figure 3: Result of different calibration hypotheses for $\ell$ Car (see text for explanation). The shaded area corresponds to an atmospheric absorption feature of ozone ( $\lambda = 9.3{-}10.0~\mu$ m, Lord 1992), where the data can be unreliable.

$\begin{figure} \par\includegraphics[width=8cm,clip]{3603fig4.eps} \end{figure}$ Figure 4: Observed squared visibilities of $\ell$ Car with VINCI, and best fit model composed of a Gaussian CSE superimposed on a limb darkened disk (solid curve). The dashed curve is a simple uniform disk model fit to the B3-M0 siderostat data only (longest baseline). The data obtained with the UTs are marked with open squares, while the siderostat data are represented by filled squares.

$\begin{figure} \par\includegraphics[width=8cm,clip]{3603fig7.eps} \end{figure}$ Figure 6: Calibrated squared visibility $V^2(\lambda )$ of $\ell$ Car using the UT2- UT3 baseline (40 m projected length). The dashed curve is the best fit Gaussian model with a FWHM of $r_{\rm CSE}(N) = 8 \pm 3$ mas. The thin, almost linear solid curve close to 100% represents the visibility function of the K band photosphere of $\ell$ Car ( $\theta _{\rm LD} = 2.70$ mas), at the phase of the MIDI observations ( $\phi = 0.901$ ).
