Peaks detected in the X-ray-detected sources spectroscopic redshift distribution, sorted by increasing redshift.
| Redshift | SX | PPoiss(N ≥ Nobj, X) | SAll | PPoiss(N ≥ Nobj, All) |
|---|---|---|---|---|
| 0.156 | 4 | 2.9 × 10−4 | 11 | 6.2 × 10−9 |
| 0.509 | 3 | 3.2 × 10−2 | 9 | 6.4 × 10−4 |
| 0.568 | 5 | 9.9 × 10−4 | 11 | 2.8 × 10−5 |
| 0.764 | 3 | 2.2 × 10−2 | 3 | 1.3 × 10−1 |
| 0.826 | 4 | 6.9 × 10−3 | 10 | 3.3 × 10−6 |
| 1.029 | 4 | 2.5 × 10−2 | 7 | 5.5 × 10−3 |
| 1.486 | 3 | 6.8 × 10−3 | 4 | 1.5 × 10−2 |
Notes. The signal and background distributions are smoothed with σS = 300 km s−1 and σB = 1.5 × 104 km s−1, respectively. “Redshift” is the central redshift of each peak, S is the number of sources in a peak, PPoiss(N ≥ Nobj) is the Poissonian probability of observing at least Nobj sources given the background value. Values marked with X are derived using the X-ray-detected sources only, while values marked with All are derived using both the X-ray sources and nonX-ray targets with a spectroscopic redshift.
