Notes. The equation that is fitted is y = a(x/c)b. Also, r is Pearson’s correlation coefficient and σ is the scatter around the best-fitting relation. Beq is the equipartition magnetic field strength, ⟨Beq⟩ is the mean equipartition magnetic field strength. Quantities denoted with ‘’ are obtained with the smoothing experiment to correct for cosmic-ray diffusion.
