Table 2.
Three redshift groups.
Group | z |
![]() |
N | Range | Bins | Med cts |
---|---|---|---|---|---|---|
lowz | 0.4–1.0 | 0.70 | 56 | 2–10 keV | 19 | 1253 |
midz | 1.0–1.7 | 1.33 | 67 | 2–14 keV | 23 | 1885 |
highz | 1.7–3.8 | 2.31 | 57 | 2–20 keV | 27 | 844 |
Notes. The table columns are redshift group, redshift range, median value of redshifts, number of sources, rest-frame energy range used, number of spectral bins, and median net counts of the spectra we use in the analysis in Sect. 4 and thereafter. Spectra of the three groups share the same energy intervals within the overlapping energy range. The column named “Med cts” is the median of the net counts, caculated as the sum of the three EPIC cameras in the respective rest-frame energy range.
