Relationship between the fraction of successful redshift predictions (with |Δz|< 0.01) and the H-band magnitude m_H. Top panel: Histogram of the number of objects as a function of m_H. Bottom panel: Fraction of successful predictions as a function of m_H for different subsets: galaxies with Hα flux greater than 10⁻¹⁷ erg/s/cm⁻² (violet line), MOONRISE-like selection (grey line), and subsets with varying exposure times of 2 h (blue), 4 h (green), and 8 h (red), along with a simulated reference trend (dashed orange line). See Sect. 4 for a detailed discussion on the behaviour of the observed trends.
