Histograms of the peak absolute magnitude in each filter. “IIn” includes the entire sample (this work, CSP, CCCP, SDSS, PS1, and PTF), while “broad” and “16aps” are shown for comparison (as in Figure 4). The vertical lines in each panel mark the median (with its value on the top right) and P_15.9–P_84.1 and P_2.3–P_97.7 ranges. The peak distributions span ≈2.6 and ≈5.0 mag in all filters at the P_15.9–P_84.1 and P_2.3–P_97.7 ranges, respectively.
