The form of the galaxy angular correlation function derived from the Edinburgh-Durham Southern Galaxy Catalogue (EDSGC) has strong theoretical consequences for models of structure formation. In this paper, we investigate the effects of Galactic extinction close to the South Galactic Pole and plate-to-plate matching errors. These represent the most probable systematic errors within the EDSGC which could affect the angular correlation function. The distribution of extinction within the EDSGC area is obtained using the Stark et al. H I map and the IRAS 100-μm flux map. We find that the amplitude of the whole EDSGC correlation function varies by less than δw=0.003 for reddening ratios R V in the range 3.25-6
