Summary of the XMM-SERVS samples and their respective photo-ɀ metrics.
| Sample | Size | w/LS10 optical CTPs | w/spec-z | Blind | w/photo-zS=−99 | 〈∆ɀ〉S | 〈∆ɀ〉P | σS | σP | ηS | ηP |
|---|---|---|---|---|---|---|---|---|---|---|---|
| ELAIS-S1 | 2630 | 931 | 324 | 234 | 44.0% | −0.028 | −0.034 | 5.5% | 6.5% | 17.6% | 22.9% |
| W-CDF-S | 4053 | 1393 | 435 | 312 | 30.0% | −0.026 | −0.109 | 5.8% | 7.5% | 16.1% | 23.9% |
| LSS | 5242 | 1299 | 630 | 431 | 65.7% | −0.130 | −0.183 | 4.8% | 8.1% | 21.3% | 28.7% |
Notes. From left to right, the columns list: Sample field; the original number of X-ray sources; the number of sources in each field that were detected in the LS10 survey; have spectroscopic redshiſt ɀ > 0.002; and were not already present in the training sample of PICZL (i.e. previously unseen); the fraction of failed photo-z in XMM-SERVS Zphot = −99; and the bias 〈∆ɀ〉, variance σNMAD and outlier fraction η obtained with XMM-SERVS (S, excluding Zphot = −99) and PICZL (P) photo-z.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
