摘要：

The angular correlation function has been computed for a two-color survey Of faint galaxies (J < 24, F < 23) covering a approximately 2.4 deg2 area near the North Galactic Pole. Faint galaxies are found to belong to a population that is more weakly clustered than luminous nearby galaxies, by a factor greater than or similar to 2 at J = 22 and greater than or similar to 4 at J = 24. Objects selected in the F (red) band are closer to model predictions than those observed in the J band. These observations are interpreted in terms of models in which (weakly clustered) bursting dwarf galaxies comprise the bulk of the number counts at faint magnitudes.
