All Tables

Table 1: Calibrators used for the observations. "SP'' stands for spectral type. Uniform Disk diameters, given in mas, are only intended for computing the expected squared visibility in the K band.
Table 2: Best fit model parameters for Polaris and its CSE. $\theta _\star$ is the stellar angular diameter (mas), $\alpha$ the CLD coefficient, $\theta _{\rm s}$ the shell angular diameter (mas), w the shell width (mas) and $F_{\rm s}/F_\star$ the relative brightness (Fig. 3). Last column tabulates the reduced $\chi ^2$ . Only parameters with error bars (lower scripts) have been fitted. The first line is the hydrostatic model; the second line is the adjusted CLD; the model of the last line includes a shell.
Table 3: Best fit model parameters for $\delta$ Cep and its CSE. $\theta _\star$ is the stellar angular diameter (mas), $\alpha$ the CLD coefficient, $\theta _{\rm s}$ the shell angular diameter (mas), w the shell width (mas) and $F_{\rm s}/F_\star$ the relative brightness (Fig. 3). Last column tabulates the reduced $\chi ^2$ . Only parameters with error bars (lower scripts) have been fitted. Note that in the second line, $\theta _{\rm s}/\theta _\star$ , $\alpha$ , w and $F_{\rm s}/F_\star$ , are set to the values found for Polaris (see Table 2).
