The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...
