Eight-fold cross-validated results of binned testing sets based on redshift. On the x-axis, we display the redshift. The points and errors are calculated by taking the mean and boundaries of each bin. In addition to the precision and recall on the left y-axis, the fraction of the data contained within the bin is plotted on the right y-axis. The y-errors represent 1σ standard deviations of the scores. The borders of the bins are [0, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6].
