Table 3: Parameters of the LkCa 15 disk derived from the model fits.
Temperature from CO isotopologues
T100 (K) $22 \pm 1$
q $0.37 \pm 0.02 $
Derived parameters from 2.8 and 1.4 mm dust emission
$R_{\rm int}$ (AU) $46 \pm 3$ [5]a
$R_{\rm out}$ (AU) $177 \pm 12$ $135 \pm 3$
$\Sigma_{100}$ (g cm-2) $3.1\pm 0.4$ $4.1 \pm 0.6$
p $1.7 \pm 0.3$ $-0.5 \pm 0.2$
$\beta$ $1.2 \pm 0.1$ $1.1 \pm 0.1$
$M_{\rm disk}$ ( ${~M}_{\odot}$) 0.029 0.025
The error bars are the $1\sigma$ formal errors (effective noise, see Sect. 2) from the fit. Two solutions are presented: one with a free inner radius, and one with a fixed inner radius of 5 AU. The dust emission is too optically thin to allow us an independent fit of the temperature, which is adopted from the CO analysis presented in Piétu et al. (2006). a Square brackets indicate fixed parameters.
