Abstract
We present percolation analyses of Wiener reconstructions of the IRAS 1.2 Jy redshift survey. There are 10 reconstructions of galaxy density fields in real space spanning the range beta = 0.1-1.0, where beta = Omega(0.6)/b, Omega is the present dimensionless density, and b is the bias factor. Our method uses the growth of the largest cluster statis tic to characterize the topology of a density held, where Gaussian ran domized versions of the reconstructions are used as standards for anal ysis. For the reconstruction volume of radius R approximate to 100 h(- 1) Mpc, percolation analysis reveals a slight ''meatball'' topology fo r the real space, galaxy distribution of the IRAS survey.
