In case the cross-correlation is determined to be unreliable (cf. Col. 41) no correction is applied and this value is therefore the same as in Col. 42 (cf. Sec. 3.2.5).

Col. 34: DEC_CORR (D) [deg]SAS task evalcorr


Corrected Declination of the source in degrees (J2000) after statistical correlation of the XMM coordinates in Cols. 42 and 43 with the USNO A2.0 source catalogue using the SAS task eposcorr. In case the cross-correlation is determined to be unreliable (cf. Col. 41) no correction is applied and this value is therefore the same as in Col. 43 (cf. Sec. 3.2.5).

Col. 35: LII_CORR(D) [deg] SAS task evalcorr


Corrected Galactic longitude of the source in degrees after statistical correlation of the XMM coordinates in Cols. 42 and 43 with the USNO A2.0 source catalogue using the SAS task eposcorr.

Corrected Galactic latitude of the source in degrees after statistical correlation of the XMM coordinates in Cols. 42 and 43 with the USNO A2.0 source catalogue using the SAS task eposcorr.

Col. 37: RADEC_ERR (E) [arcsec] SAS task srcmatch


Statistical 1 sigma error on the source position in arcseconds. It is associated with the weighted mean RA and Dec coordinates as calculated by the SAS task srcmatch (Cols 42 and 43, cf. Secs. 3.2.4 and 6.4).

Col. 38: SYSERRCC (D) [arcsec] SAS task evalcorr


The systematic 1 sigma error on the source position in arcseconds. It is set to be 0.arcsec5 if the SAS task eposcorr (cf. Col. 40) results in a statistically reliable cross-correlation with USNO A2.0 optical catalogue. Otherwise the error is 1.arcsc5 (see Col. 41 and Sec. 3.2.5 for details).

Col. 39: NMATCHES (I) SAS task eposcorr


The number of matches between the USNO A2.0 coordinates and the detections of this XMM observation in the eposcorr cross-correlation (see Col 40 and Sec. 3.2 5).

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.
