We consider whether photometric errors may have produced the large-scale power in the APM galaxy correlation function. Using the CCD galaxy sequences that are available on 39 of the 185 Schmidt fields of the APM survey, we apply an analysis of variance to make an independent estimate of the size of the zero-point errors associated with the APM galaxy photometry. The method finds an rms dispersion for these errors of 0.084 mag, a factor of 2 larger than previously claimed. Furthermore, we present evidence that this error may also be spatially correlated over the large APM survey area and show that the tests carried out by the APM/Oxford group could be insensitive to such large-scale effects
