a) Photometric redshift determined with the ANN (zNN) as a function of the redshift measured from spectroscopy (zspectro). b) The zNN − zspectro distribution is fitted with three Gaussians contributing 93.4%, 6.4%, and 0.2% of the histogram and of width σ = 0.1, 0.4, and 1.0, respectively. The rms of the zNN − zspectro distribution is 0.18 and its mean is 0.00.
