Distribution of the number of spiral arms identified from visual classification, using a threshold of four out of six classifiers for agreement. The undefined category refers to systems where classifiers agreed that no specific number of spiral arms could be discerned. The y-axis represents the fraction of spiral galaxies in each redshift bin, normalized by the total number of classified spiral galaxies in that bin. The blue bars correspond to galaxies in the 0.8 < z < 1.3 range, while the orange bars represent galaxies in the 2.0 < z < 2.5 range. Numbers displayed above the bars indicate the absolute counts of galaxies in each category. The green diamonds correspond to the debiased fractions from the luminosity-limited sample of Hart et al. (2016).
