Quantifying large-scale structure 75Figure 2.10.The nonlinear evolution of various CDM power spectra, as determined by
the Virgo consortium (Jenkinset al1998). The broken curves show the evolving spectra
for the mass, which at no time match the shape of the APM data. This is expressed in the
lower small panels as a scale-dependent bias atz=0:b^2 (k)=PAPM/Pmass.
Integrating along the redshift axis then gives theprojected correlation function,
which is independent of the velocities
