Growth of correlations in the real space power spectrum

The correlations in real space power between the bands centred at the
indicated wavevector k and k = 0.17 h Mpc-1.
The correlations are shown for three different redshifts: z = 0.5 (circles),
z = 0.3 (triangles), and z = 0 (squares). The correlations grow with time,
reaching over 50% at high k. (From Meiksin & White 1999, MNRAS, 308, 1179.)
