between 0.3 and 3keV. The [edetect\_chain]{} task was used to find sources with a combined maximum likelihood value in all three instruments greater than 10 for the 0.3-3.0keV energy range. We expect 1-2 spurious X-ray detections at this level of significance, though they would be highly unlikely to correlate with an NGC 2547 member, so will not hamper any analysis in this paper.

Before performing the combined search we executed searches on the individual images to confirm that there were no systematic differences in the astrometry of the brightest sources. Count rates in each detector were determined for sources using exposure maps created within the same task. In addition, count rates were determined for each source in the 0.3–1.0keV and 1.0–3.0keV bands separately. A total of 163 significant X-ray sources were found. Some only have count rates measured in a subset of the three instruments because they fell in gaps between detectors, on hot pixels or lay outside the field of view.

Source Identification

Jeffries & Tolley (1998) showed that the majority of bright X-ray sources in this region are associated with stars in the NGC 2547 cluster. As the purpose of this paper is to examine the X-ray
