The following should be better, but could include a couple that are really a bit too far apart for real association... I didn't test against the 1RXP [ROSAT point source cat] list, as it has multi-epoch detections, which means more than one entry per source in the catalogue, and involves a bit more fiddling. Rather than just showing that ROSAT cats can have non-CV candidates, I thought that those more familiar with xray data taxonomy [hardness ratios etc] may be able to assess PT Per's data with respect to other known CVs in the Faint Source catalogue.
