Table 11
List of additional database parameters in the multiwavelength tables (in addition to the X-ray columns marked with a tick in column “o” of Tables 9 and 10).
| Column name | Units | Explanation |
|---|---|---|
| Columns appearing once | ||
| seq | – | Sequential counter of the counterpart set (kept internally but not provided) |
| Ctpra,Ctpdec | ° | Counterpart coordinates from the closest survey |
| Columns appearing once for each survey. Survey mnemonics surv are given in Table 4 | ||
| survseq | – | Seq pointers to the various photometric tables (kept internally but not provided) |
| survra,survdec | ° | Counterpart coordinates in the individual survey |
| survdist | ′′ | X-ray to counterpart distance |
| Columns appearing per survey and per band. Band (filter) mnemonics per survey are given in Table 4 | ||
| survmagband | AB mag | 3′′ aperture magnitude in given band for given survey |
| survmagband_e | AB mag | Error on magnitude |
| Again columns appearing once | ||
| Xrank | Identification rank (see main text) | |
| Pbest | – | Best band (smallest) chance probability (formula 1) |
| LRbest | – | Best band (highest) likelihood ratio (formula 2) |
| zspec | – | Spectroscopic redshift |
| origin | Origin of zspeca | |
| simbadId | – | SIMBAD identifier (may be one of many) |
| nedId | – | NED identifier (may be one of many) |
| star | 0|1|2|3 | Star flag: 1 if zspec = 0, 2 by visual inspection, 3 both |
| agn1000 | −1|0|1 | 1 if counterpart in XXL Paper VI is confirmed, −1 if X-ray source is listed in Paper VI |
| but counterpart changed, 0 if X-ray source not listed in Paper VI | ||
