Caption: Figure 2.

Left: image of the raw data from the Chandra ACIS S2 CCD. The data have been binned to 2'' pixels and Gaussian-smoothed with a 3 pixel kernel radius to a final scale of 0.2–90 counts pixel−1. The white ellipsoidal region labeled "Source" is used for spectral analysis with regions labeled "BG" serving as background subtraction regions. Right: a close-up of the central emission using the same binning and smoothing parameters. Cyan contours outline the emission at 1.0, 1.8, 2.5, 20, and 40 counts pixel−1. The red ellipse is the 6σ error ellipse for the point-source position, as detected using the CIAO tool wavdetect.
