摘要：

We present the first measurement of the angular correlation function in a K-selected galaxy survey, from two fields covering almost 10 deg(2). The angular correlation function at small angles is well described by a theta(-0.8) power law, as for optically selected samples. The clustering amplitude is reduced by a factor of similar to 4 between galaxies with K <15 and a fainter magnitude slice with 15 <K <16. This allows us to place constraints upon the redshift distribution of the galaxies and their spatial correlation function. We find no clear evidence for a change in clustering amplitude when galaxies are selected by their observed B-K colours.
