Table 6: The stellar parameters for the sample sources. The distance d which we used in the analysis and spectral type (Sp. T.) are given. The visual extinction $A_{\rm V}$, the logarithm of the effective temperature $\log T_{{\rm eff}}$, of the stellar luminosity $\log L$, of the stellar UV luminosity $\log L_{{\rm uv}}$ and of the observed bolometric luminosity $\log L_{{\rm bol}}$ are presented as well. The latter quantities are estimated based on the photometric measurements. Furthermore, the ratio of the IR excess luminosity over the stellar luminosity is computed. Ten of the sample sources have a ratio larger than unity, hence are not consistent with a passive reprocessing disk. The last 4 columns contain the IR excess fluxes in K (2.2 $\mu $m), at 60, 850 and 1300 micron. $^\bigstar $ These stars are UX Orionis objects according to the definition of Dullemond et al. (2003). $^{\spadesuit }$ Probable confusion with the nearby source CrA IRS7.
