Histograms of the number of frames per stack in g-band. In the top panel, the gray histogram shows the average distributions over the entire HSC PDR2 footprint, and the orange filled histogram shows the distributions restricted to the GAMA09H field. In addition, the step histogram shows the distributions for galaxies within GAMA09H assigned the 1% highest scores by the ResNet from C21. In the bottom panels, orange curves show the excess of the 1% top scores, obtained from the difference between the step and filled orange histograms in the top panels, and other curves showing additional networks.
