(see Col. 41 and Sec. 3.2.5 for
details).Col. 39: NMATCHES (I) SAS task eposcorr

The likelihood of the statistical fit to the cross-correlation of source matches of detections of this XMM observation with the USNO A2.0 coordinates using the SAS task eposcorr (their eq. 1). If the fit is reliable (see Col. 41), the resultant correction is used to rectify the RA and Dec coordinates from the observation source lists (Cols. 42 and 43) For a more detailed description see Sec. 3.2 5 and the SAS task documentation on eposcorr.
Col. 41: POSCOROK (L) SAS task evalcorr
The value is set to True if the SAS task evalcorr that evaluates the likelihoods in Col. 40 signals a reliable and statistically significant improvement in the source position. If the probability of improvement is only marginal, it is set to False. For details of the evaluation procedure see Sec. 3.2 5 and the SAS task documentation on evalcorr.
