Coordinates (9 columns)

RA (D) [deg] SAS task evalcorr
Corrected Right Ascension of the detection in degrees (J2000) after statistical correlation of the emldetect coordinates, RA_UNC and DEC_UNC, with the USNO B1.0 optical source catalogue using the SAS task eposcorr. In case where the cross-correlation is determined to be unreliable no correction is applied and this value is therefore the same as RA_UNC (cf. Sec. 2XMM UG, Sec. 3.1.3).
DEC (D) [deg]SAS task evalcorr
Corrected Declination of the detection in degrees (J2000) after statistical correlation of the emldetect coordinates, RA_UNC and DEC_UNC, with the USNO B1.0 optical source catalogue using the SAS task eposcorr. In case where the cross-correlation is determined to be unreliable no correction is applied and this value is therefore the same as DEC_UNC (cf. Sec. 2XMM UG, Sec. 3.1.3).
POSERR (E) [arcsec]
Total position uncertainty in arcseconds calculated by combining the statistical error RADEC_ERR and the systematic error SYSERR as follows: POSERR = SQRT ( RADEC_ERR2 + SYSERR2 ).
LII (D) [deg] SAS task evalcorr
Galactic longitude of the detection in degrees corresponding to the (corrected) coordinates RA and DEC.
BII (D) [deg] SAS task evalcorr
Galactic latitude of the detection in degrees corresponding to the (corrected) coordinates RA and DEC.
RADEC_ERR (E) [arcsec] SAS task emldetect
Statistical 1 σ error on the detection position in arcseconds.
SYSERR (E) [arcsec]
The estimated systematic 1 σ error on the detection position in arcseconds. It is set to be 0."35 if the SAS task eposcorr results in a statistically reliable cross-correlation with USNO B1.0 optical catalogue. Otherwise the error is 1."0 (see Sec. 2XMM UG, Sec. 3.2.2 for details).
RA_UNC (D) [deg] SAS task emldetect
Right Ascension of the source in degrees (J2000) as determined by the SAS task emldetect by fitting a detection simultaneously in all cameras and energy bands.
DEC_UNC (D) [deg] SAS task emldetect
Declination of the source in degrees (J2000) as determined by the SAS task emldetect by fitting a detection simultaneously in all cameras and energy bands.
