Popis:	We have constrained the redshift-distortion parameter $beta equiv Omega^{0.6}/b$ and the real-space power spectrum of the IRAS PSCz survey using a spherical-harmonic redshift-distortion analysis combined with a data compression method which is designed to deal with correlated parameters. Our latest result, $beta=0.4 pm 0.1$, strongly rules out $beta=1$.
