Cosmological Parameters from the Eigenmode Analysis of the Las Campanas Redshift Survey.
We present the first results of the Karhunen-Loève eigenmodes applied to real data of the Las Campanas Redshift Survey to simultaneously measure the values of the redshift distortion parameter beta=Omega0.60&solm0;b, the linearly extrapolated normalization sigmaL8, and the cold dark matter shape parameter Gamma=Omega0h. The results of our numerical likelihood analysis indicate a low value of beta=0.30+/-0.39, a shape parameter Gamma=0.16+/-0.10, and a linearly extrapolated normalization sigmaL8=0.79+/-0.08, which are consistent with a low-density universe (Omega0 less, similar0.5).
