Parameters for four different cosmological models. The columns are (1)
Model number (C = concordance cosmology), (2) total mass density
parameter, (3) vacuum energy density parameter, (4) baryonic mass
fraction, (5) present day Hubble constant in units of 100 km/s/Mpc,
(6) slope of the primordial density perturbation power spectrum, (7)
the fluctuation normalization at z = 0 in a sphere of radius 8 Mpc/h,
(8) fluctuation normalization at z = 3 filtered on the isothermal
Jeans scale for gas at T = 20 000 K (as defined in Meiksin, Bryan &
Machacek 2001, MNRAS, 327, 296).(From Meiksin & White 2004, MNRAS, 350, 1107.)
