All Tables

Table 1: Methods for determining $N_{\rm H}$ /A_V ratios.
Table 2: Chandra data used in this work.
Table 3: X-ray properties of Class III sources in $\rho$ Oph, IC 348, R CrA, Cha I and Orion Nebula observed with Chandra, and X-ray properties of Class III sources in $\rho$ Oph observed with XMM-Newton (using the default standard solar ISM abundances in XSPEC). Multiple entries of T correspond to a multiple temperature model.
Table 4: Comparison between A_J, and our SED blackbody temperature fitting with those from Luhman & Rieke (1999) for the $\rho$ Oph sources.
Table 5: The $N_{\rm H}$ /A_V ratios from the literature (see also Table 1).
