We reanalyzed calibrated radio flux-density measurements for 897 pulsars using Bayesian model comparison alongside frequentist methods. Broken power laws were the most common spectral form, accounting for 60% of the sample, while simple power laws described 13.5%; in total, 68.8% of pulsars decisively favored curved or broken models.
The study also identifies 74 confident gigahertz-peaked-spectrum pulsars and finds that spectral curvature is frequent among millisecond pulsars. Comparing the statistical methods shows that the previously reported dominance of simple power laws was largely methodological rather than astrophysical.
