摘要
Despite many independent estimates, there has been little consensus reached as to the form of the two-point angular correlation function of galaxies. We present the two-point angular correlation function for the recently completed Edinburgh-Durham Southern Galaxy Catalogue. This galaxy survey consists of digitized COSMOS scans for 60 UK Schmidt fields centred at the South Galactic Pole. Both star-galaxy classification errors and photometric errors in plate-to-plate matching, that could ruin a project of this kind, have been kept to a minimum. The catalogue is therefore ideally suited to probe the form of the correlation function on cosmologically interesting scales. We present our w(theta) results from the catalogue at four depths: b(j) = 17.5, 18.5, 19.5 and 20.3. These correlation functions all indicate significant power out to scales congruent-to 30 h-1 Mpc. This is in conflict with the result obtained from the analysis of the Lick survey of galaxies and is consistent with recently reported galaxy correlation functions.
