Parameters of the cylinder parametric model, and of the simulated box as a function of redshift. Left panel: cylinder diameter D_s in comoving coordinates for three different angular sizes θ = 5, 10, and 15 arcmin. Middle panel: cylinder length as comoving distance between two redshifts z − δ_z/2 and z + δ_z/2 for three different values of δ_z as noted. The length of the simulation box is shown with a dotted black line. Right panel: redshift interval δ_z corresponding to the size of one simulation box L_box = 205 Mpc h⁻¹.
