| Contains the parameters provided for each source in the 2XMMi-DR3 catalogue v. 1.0 |
| The XMM-Newton serendipitous source catalogue, as described at http://xmmssc-www.star.le.ac.uk/Catalogue/xcat_public_2XMMi-DR3.html is contained in this table. See the above URL for further details. Required constraints:
|
| Name | Type | Length | Unit | Description | Default Value | Unified Content Descriptor |
|---|---|---|---|---|---|---|
| DETID | int | 4 | A consecutive number which identifies each entry (detection) in the catalogue. | |||
| SRCID | int | 4 | 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 on the two-sigma level of both positional errors. A maximum distance of 7" was assumed, which was reduced to 0.9 * DIST_NN (distance to the nearest neighbour) where necessary. | |||
| SRCID_2XMMi | int | 4 | The unique source ID of the detection, DETID, in the 2XMMi catalogue. Due to the nature of the matching algorithm, some detections were re-assigned to a different source due to the presence of new detections. | |||
| IAUNAME | varchar | 30 | The IAU name assigned to the unique SRCID. | |||
| SRC_NUM | int | 4 | The (decimal) source number in the individual source list for this observation; in the hexadecimal system it identifies the source-specific product files belonging to this detection. | |||
| OBSID | varchar | 10 | The XMM-Newton observation identification. | |||
| REVOLUT | varchar | 4 | orbit | The XMM-Newton revolution number. | ||
| MJD_START | float | 8 | days | Modified Julian Date (i.e., JD - 2400000.5) of the start of the observation. | ||
| MJD_STOP | float | 8 | Modified Julian Date (i.e., JD - 2400000.5) of the end of the observation. | |||
| OBS_CLASS | int | 4 | Quality classification of the whole observation based on the area flagged as bad in the manual flagging process as compared to the whole detection area. 0 means nothing has been flagged; 1 indicates that 0% < area < 0.1% of the total detection mask has been flagged; 2 indicates that 0.1% <= area < 1% has been flagged; 3 indicates that 1% <= area < 10% has been flagged; 4 indicates that 10% <= area < 100% has been flagged; and 5 means that the whole field was flagged as bad. | |||
| PN_FILTER | varchar | 6 | PN filter. The options are Thick, Medium, Thin1, Thin2, and Open, depending on the efficiency of the optical blocking. | |||
| M1_FILTER | varchar | 6 | M1 filter. The options are Thick, Medium, Thin1, and Open, depending on the efficiency of the optical blocking. | |||
| M2_FILTER | varchar | 6 | M2 filter. The options are Thick, Medium, Thin1, and Open, depending on the efficiency of the optical blocking. | |||
| PN_SUBMODE | varchar | 23 | PN observing mode. The options are full frame mode with the full FOV exposed (in two sub-modes), and large window mode with only parts of the FOV exposed. | |||
| M1_SUBMODE | varchar | 16 | M1 observing mode. The options are full frame mode with the full FOV exposed, partial window mode with only parts of the central CCD exposed (in different sub-modes), and timing mode where the central CCD was not exposed ('Fast Uncompressed'). | |||
| M2_SUBMODE | varchar | 16 | M2 observing mode. The options are full frame mode with the full FOV exposed, partial window mode with only parts of the central CCD exposed (in different sub-modes), and timing mode where the central CCD was not exposed ('Fast Uncompressed'). | |||
| RA | float | 8 | degrees | 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. | ||
| DEC | float | 8 | degrees | 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. | ||
| POSERR | real | 4 | 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 ). | ||

| BII | float | 8 | degrees | Galactic latitude of the detection in degrees corresponding to the (corrected) coordinates RA and DEC. | ||
| RADEC_ERR | real | 4 | arcsec | Statistical 1 σ error on the detection position in arcseconds. | ||
| SYSERR | real | 4 | arcsec | The systematic 1 σ error on the detection position in arcseconds. It is set to be 0.35 arcsec if the SAS task eposcorr results in a statistically reliable cross-correlation with USNO B1.0 optical catalogue. Otherwise the error is 1.0 arsec. | ||
| RA_UNC | float | 8 | degrees | 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 | float | 8 | degrees | 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. | ||
