Logarithm of the redshift vs. R_F for all galaxies with acceptable redshifts (q > 2) in each of the four fields. Different symbols are used to represent an object's inclusion in the statistical samples: triangles, included in the statistical sample, with either N_b = 0 or N_b = −1; squares, included in the statistical sample, with N_b > 0; circles, not part of the statistical sample, but was a special target of a multiaperture mask; crosses, not part of the statistical sample. Objects 308890 (5 log z = −12.614, R_F = 12.58) and 307977 (5 log z = −12.343, R_F = 16.88) are beyond the lower edge of the plot for Herc 1.
