Scientific paper

The paper presents angular correlation functions for samples of galaxies found by measurement of five Schmidt plates with the COSMOS machine. The plates include J-R pairs of two fields and have been limited to J=21.5 and R=19.75 at various magnitudes. On small angular scales, the amplitudes of the correlation functions are in agreement with those expected from the scaling of local results, indicating the uniformity and isotropy of the universe to very great depths. However, the errors are still too large to impose useful constraints on evolution in galaxy clustering. At large angular scales evidence is found for the correlations similar to those of Groth and Peebles (1977) in the analysis of the Lick catalog; its position corresponds to a physical separation of 3/h Mpc, three times smaller than that of Groth and Peebles.
