Table 5
Fit of the mass function (dn/dM/dz) for haloes selected as in Fig. 11.
| Parameter | Ωm | σ8 | w0 |
|---|---|---|---|
| fiducial | 0.23 | 0.83 | –1 |
| Fit of the mass function (best-10 values) | 0.227 | 0.828 | –0.981 |
| Fisher predictions | ±0.0001 | ±0.004 | ±0.031 |
Notes. Uncertainties on the mass measurements are assumed to be null. The errors predicted by the FA assume that the real (Aardvark) Universeand the fitted model have exactly the same mass function (namely Tinker), hence indicate the shot noise level for a 700 deg2 area. The comparison between the Fisher predictions and the fit results provides an estimate of the impact of the Tinker hypothesis for this particular halo sample.
