Table 4: Spectral parameters of bright X-ray sources in the Cha I XMM-Newton field. The columns represent: source number, identification, number of counts in the background-subtracted spectrum, reduced $\chi ^2$ of best fit, absorbing hydrogen column density derived from A_J using the relation by Paresce84.1 and held fixed during the fitting process, X-ray temperature(s) of 2-component thermal MEKAL model, and emission measures of each temperature component assuming a distance of 160 pc.
