All Tables

Table 1: Mass and radius determination for $\kappa$ CMa from the Harmanec (1988) compilation for the effective temperatures given by Popper (1980), Prinja (1989) and Fremat (2005).
Table 2: Calibration star diameters estimated from spectro-photometric indices (computed as in Bonneau et al. 2006) and their associated errors.
Table 3: Br $\gamma$ visibilities measured in the continuum ( $V_{\rm c}$ ) and visibility drop within the Br $\gamma$ line ( $V_{\rm r}$ / $V_{\rm c}$ ). $V_{\rm r}$ calculated from the measured $V_{\rm c}$ and $V_{\rm r}$ / $V_{\rm c}$ ratio. The deduced envelope contribution in the continuum ( $V_{\rm ec}$ ) and in the line ( $V_{\rm er}$ ) is given for each baseline. The corresponding angular diameters in the Br $\gamma$ line ( $\phi _{\rm er}$ ) and the nearby continuum ( $\phi _{\rm ec}$ ) are computed using a uniform disk model for each envelope measurement. The corresponding extension in stellar radii are also given, assuming a 6 $R_\odot$ star at 230 pc.
Table 4: Parameters for the $\kappa$ CMa central star and its circumstellar environment for the best axi-symetric model.
