摘要
We investigate the accuracy achievable on measurements of the the growth rate of structure f (z) using redshift-space distortions (RSD), when (a) these are measured on the group-galaxy cross correlation function; (b) the latter is expanded over a modified version of the conventional spherical armonics, "truncated multipole moments". Simulation results give first indications that this combination can push systematic errors on f (z) below 3%, using scales r >= 10h(-1)Mpc.
