Behaviour of the correlation coefficient for different redshift pairs (z_ji,z_j) ∈  { (30,10);(30,5);(30,1);(30,0) }  for all six wavelet levels. We see that for the largest smoothing scale, i.e. w6, all the correlators stay very close to r = 1. At lower wavelet levels, as the redshift drops below z = 30, the lines start to deviate from r = 1. Thus, on the largest scales the information is approximately preserved, while on the smallest scales the information is gradually erased.
