Photometric vs. spectroscopic redshift comparison. Gray crosses indicate the OTELO template fitting photometric redshifts and filled red circles the neural network estimates. The regression lines for the different fits – not plotted – are barely distinguishable from the perfect correlation between photometric and spectroscopic redshifts (blue-solid thick line). The blue-dashed thin lines show the Hildebrandt et al. (2010) outlier limits.
