Open Access

Table 4

Estimation of σ₈ parameter from mass and shape measures in dark energy simulations (see main text).

Model	ΛCDM	RPCDM	wCDM
Exact $σ_{8}^{G a u s s}$ $\[\sigma_{8}^{Gauss}\]$	0.83	0.68	0.88
Estimated $\bar{σ_{8}^{G a u s s}}$ $\[\overline{\sigma_{8}^{Gauss}}\]$	0.79	0.62	0.85

Notes. The exact value, taken from direct integration of the linear power spectrum is also reported for comparison.
