Notes.
Weighted mean results from the SED Fitting tool by Robitaille et al. (2007).
Standard deviation of the weighted mean values are reported here. χ2 values are used to weight the fits. A minimum of 10 fits from the defined best-fit criteria was required to calculate the weighted mean values.
0: deeply embedded, 1: Class I, 2: Class II, F: Flat spectrum, 3: transition disks.
Values in parentheses signify error in last two digits of the SED slope value.
