Table 2: Differential number counts, N, and surface density, n (in arcmin-2), of Lyman-break galaxies in the CFDF fields, for a range of IAB-selected slices. The mean surface density, labelled CFDF, is also given. Errors in the surface density measurements for each individual field are computed using Poisson counting statistics; field-to-field variance is used to estimate the error in the mean.
