Abstract  We have investigated the statistical clustering properties of galaxies by calculating the twopoint galaxy correlation function from the optically selected Durham/ UKST Galaxy Redshift Survey. This survey is magnitudelimited to bJ ∼ 17, contains ∼ 2500 galaxies sampled at a rate of oneinthree and surveys a ∼ 4 × 106 (h1 Mpc)3 volume of space. We have empirically determined the optimal method of estimating the twopoint correlation function from just such a magnitudelimited survey. Applying our methods to this survey, we find that our redshiftspace results agree well with those from previous optical surveys. In particular, we confirm the previously claimed detections of largescale power out to ∼40 h1 Mpc scales. We compare with two common models of cosmological structure formation and find that our twopoint correlation function has power significantly in excess of the standard cold dark matter model in the 1030 h1 Mpc region. We therefore support the observational results of the APM galaxy survey. Given that only the redshiftspace clustering can be measured directly, we use standard modelling methods and indirectly estimate the realspace twopoint correlation function from the projected twopoint correlation function. We then invert this projected correlation function to obtain an estimate of the spatial twopoint correlation function in real space. This correlation function in real space has a lower amplitude than that in redshift space, but a steeper slope.
