Object parameters derived from fitting the data points to YSO SEDs (see Sect. 3.2). Column (1) lists the ID of the object, corresponding to the entry in Table 1. Column (2) indicates whether the source is thought to be spatially associated with the IRDC filament. The number of available data points, N, is listed in Col. (3). The $\chi^2$ per data point, $\chi^2/N$, is given in Col. (4). Columns (5)-(7) list the fitted stellar mass, envelope accretion rate and disk mass, respectively. Note that the latter two are given in terms of $M_\star$, not $M_\odot$. Finally, Col. (8) lists the Stage in which the sources fall according to the values in Cols. (6) and (7) and the Stage definition in Table 3. If multiple possibilities are given for the Stage of a source, the less likely one(s) is (are) presented in brackets. A ``$\sim$'' prefix in Cols. (5)-(7) or (8) indicates a high uncertainty in the derived parameter, resulting either from a high value of the minimal $\chi^2/N$ and/or a large spread in fitted parameter values.
