Distribution of some relevant parameters of the training and testing data. In the top row, number counts are in linear scale, while in the bottom row number counts are in logarithmic scale. The first panel on the left shows the original spectroscopic sample of the 148 521 galaxies collected in KiDS+VIKING. However, only the 134 148 galaxies located between the two vertical dashed lines (spec-z = 0.04 and spec-z = 3) are used in this work for training and testing the GaZNets. For these galaxies, we show the MAG_AUTO and S/Ns in the second and third panels.
