QSO catalogues used in this analysis.
| Survey | Redshift Range | Objects | Median z |
|---|---|---|---|
| eBOSS DR14 QSO | 0.4 < z < 2.8 | 187 954 | 1.59 |
| eBOSS DR16 QSO | 0.8 < z < 2.2 | 343 708 | 1.51 |
| DESI DR1 QSO | 0.8 < z < 3.0 | 1 176 570 | 1.75 |
Notes. The redshift ranges are selected to focus on the well-sampled core of each distribution while minimizing edge effects (see Figure 1).
