Matching x-ray detections by XMM1 and ChaMP, and associated optical objects Notes: (1) Count rates of XMM1 and ChaMP have been normalized to ROSAT PSPC standard. ChaMP flux x30, and XMM1 counts x0.225 to reach the PSPC standard. (2) A "GOOD" optical object is one which lies within 2 arcsec (incl) of the positional uncertainty. This accounts both for rounding and the typical 1 arcsec error of our optical astrometry. (3) XMM1 and ChaMP sources have been de-duplicated where there were any within 5 arcsec, and the strongest source retained. (4) It is considered that XMM1-ChaMP pairing offset further than 11 arcsec are not actually matches but represent different sources; however these are displayed here for consistency. Matches are displayed in order of offset in arcsec, so the far-apart ones are at bottom.
