摘要：

We have completed a uniform catalog of galaxies of 386 deg2, containing 150,000 galaxies based on plates obtained for the second epoch Palomar Observatory Sky Survey (POSS-II). This catalog is divided into two well-separated regions of sky. We have measured the two-point angular correlation function for each field and find excellent agreement on small angular scales, but disagreement on scales larger than 0.5-degrees. This disagreement is larger than can be accounted for by known systematic errors and so indicates a real difference in the large-scale structure of the two samples. Only one of the two fields is consistent with the result from the APM survey.
