Scientific paper

We present a formalism for analysing redshift distortions based on a
spherical harmonic expansion of the density field. We use a maximum likelihood
estimator for the combination of density and bias parameters, $\Omega^0.6/b$.
We test the method with $N$-body simulations and apply it to the 1.2 Jy IRAS
redshift survey.
