Histogram of spectroscopic redshifts obtained from S/N > 5 emission lines. The separate histograms are for the medium-dispersion R ≈ 1000 gratings (flag A, darkest purple), additional galaxies with S/N > 5 emission lines detected with the low-dispersion R ≈ 30–300 prism (flag B, lighter purple histogram) and galaxies with more marginal redshifts (flag C, lightest histogram).
