We present a correlation function analysis for the catalogue of photometric redshifts obtained from the Hubble Deep Field image by Fernandez‐Soto, Lanzetta & Yahil. By dividing the catalogue into redshift bins of width Δ z =0.4 we measured the angular correlation function w ( θ ) as a function of redshift up to z ∼4.8. From these measurements we derive the trend of the correlation length r 0 . We find that r 0 ( z ) is roughly constant with look‐back time up to z ≃2, and then increases to higher values at z ≳2.4. We estimate the values of r 0 , assuming ξ ( r , z )=[ r r 0 ( z )] − γ , γ =1.8 and various geometries. For Ω 0 =1 we find r 0 ( z =3)≃7.00±4.87 h −1 Mpc, in good agreement with the values obtained from analysis of the Lyman break galaxies.
