Parameter explanations

Lbox : side length of the simulation box, usually in Mpc/h or kpc/h
h: Hubble parameter, dimensionless
ΩΛ : density parameter for dark energy
Ωm : density parameter for matter (= mean density/critical density)
Ωbar : density parameter for baryons
σ8 : amplitude of matter fluctuation averaged over spheres of 8 Mpc/h in size
n: normalization of the power spectrum
seed: random number seed for generating initial conditions
