Identification of the source

Col. 1: SRCINDEX (J)

A consecutive number which identifies each entry in the catalogue.

Col. 2: UNIQUE_SRCNUM (J)

A unique number assigned to a group of catalogue entries which are assumed to be the same source. To identify members of the same group the distance in arcseconds between each pair of sources was compared with four times the combined error of the statistical error, Col. 37, and systematical error, Col. 38, of the two sources (see Sec. 4.4.1 for a more detailed description).

Col. 3: XMMSRCNAME (21A)

The IAU name for this entry (see Sec. 4.4.1).

Col. 4: SUM_SRC_NUM (J) SAS task srcmatch


The source number in the summary source list for this observation (see the products P<obsid>EPX000OBSMLI0000.FIT with <obsid> from Col. 8). This list was merged from the source lists for each exposure (see Cols 5-7) where sources with coinciding positions are identified as being the same (cf. Sec. 2.2.4).

Col. 5: PN_ML_ID_SRC (J) SAS task emldetect


Source number in the PN source list for this exposure (see the products P<obs-id>M1<exp-id>EMSRLI0000.FIT with <obs-id> from Col. 8 and <exp-id> from Col. 18; cf. Col. 30).

Col. 6: M1_ML_ID_SRC (J) SAS task emldetect


Source number in the M1 source list for this exposure (see the products P<obs-id>M1<exp-id>EMSRLI0000.FIT with <obs-id> from Col. 8 and <exp-id> from Col. 19; cf. Col. 31).

Col. 7: M2_ML_ID_SRC (J) SAS task emldetect


Source number in the M2 source list for this exposure (see the products P<obs-id>M1<exp-id>EMSRLI0000.FIT with <obs-id> from Col. 8 and <exp-id> from Col. 20; cf.Col. 32).
