Survey designs modelled in this work.
| Survey | A | B |
|---|---|---|
| Area (deg2) | 50 | 200 |
| Depth (ks) | 80 | 20 |
| Optimal detection aperture Ropt (arcsec) | 8. | 11. |
| Limiting Athena/WFI count rate CRlim (r < Ropt) (c s−1) | 7.01 × 10−4 | 2.19 × 10−3 |
| Number of clusters in 0 < z < 2 | 5500 | 11 200 |
| Number of clusters in 1 < z < 2 | 940 | 1400 |
Notes. A and B share the same total exposure time (≈9 Ms for Athena/WFI). Survey A is similar to the planed generic Athena/WFI AGN survey.
