All Tables

Table 1: Properties of the three Herbig Ae stars observed with the CAMIRAS mid-InfraRed camera. First two columns: coordinates of the objects (right ascension and declination); third column: their spectral type; fourth column: their distance, as deduced from Hipparcos data; fifth column: flux in the IRAS 25 $\mu$ m band; sixth column: flux at 20 $\mu$ m obtained in this paper; seventh column: age of the objects in Myr.
Table 2: Parameters of the elliptical fit of the image. In the first column, the inclination of the disk (0 degree means a faced-on disk). The position angle (PA) of the disk on the sky is measured counter-clockwise from the North. The distance corresponds to the maximum distance at which the disk is detected in the 20 $\mu$ m observations. The brightness level in the last column corresponds to the brightness of the maximum distance at which the disk is detected here.
Table 3: Stellar properties and fit parameters. The stellar parameters of CQ Tau are taken in Chiang et al. (2001). For HD 135344 and HD 163296, the parameters are taken from Meeus et al. (2001) and van Boekel et al. (2005). $H_{p}^{\rm in}/R_{\rm in}$ characterizes the puffed inner rim. q is the power-law index of the scale height and p that of the surface density. $H_{\rm p}^{\rm out}/R_{\rm out}$ characterizes the flaring angle of the disk. The last column is the flux at 20.5 $\mu$ m calculated from the modeled image.
Table 4: Effects of the free parameters of the model on the SED and spatial distribution of the 20.5 $\mu$ m emission in the CAMIRAS image.
