CNN membership prediction (run) together with spectroscopic sources, represented as (i) CLMs distribution of F814 magnitudes (first row), (ii) differential colour – magnitude sequence for both CLMs and NCLMs. Spectroscopic CLMs are shown in green, candidate members in purple, spectroscopic NCLMs with blue squares and candidate NCLMs with open cyan circle. We only plot CNN cluster members with F814 ≤ 25 mag. The grey region within the CM diagrams limits the area corresponding to ±1σ from the median (dashed horizontal line) of (F606 − F814)_diff.
