Chandra observation of a crowded field near the center of the Orion Nebula Cluster. This field is approximately ﹩25\prime\prime \times 25\prime\prime ﹩ in size, and is centered at (R.A., decl.)=(5:35:15.4,-05:23:04.68). Shown in blue are approximate 90% posterior credible regions for source locations, under the spatial-only model (left), and the extended full model (right). The figures next to the regions indicate the estimated relative intensities. The credible region of the source with the largest location uncertainty is circled in green (right panel). The red rectangular box encloses two overlapping sources (right panel) for which we carry out a detailed follow-up spectral analysis (Section 7.2).
