Global parameters for the three types of fields simulated in this study.
| Equatorial | Intermediate | Deep | |
|---|---|---|---|
| Texp | ∼1.6 ks | ∼4 ks | ∼9.7 ks |
| ΔTexp max. | 0% | 16% | 33% |
 (cm−2) |
3 × 1020 | 8.8 × 1020 | 6.3 × 1020 |
| flim (cgs) | 3 × 10−15 | 10−15 | 2 × 10−16 |
Notes. Each field is a square of 3.6 deg × 3.6 deg. The galactic absorption is assumed uniform with a value 
. AGNs are simulated individually down to a flux flim in the 0.5–2 keV band and sources below flim contribute to a diffuse background component. The maximal variation of exposure across a field is listed as ΔTexp = (Tmax − Tmin)/Tmean.
