Segments of the size-frequency relations for catalogs RGO, SOON, PCSA, KMAS: ipf φ₁ (circles) are shown together with theoretical values calculated for the power law distribution on the interval [a,b], where [a,b] is [10, 1000], [100, 1000], [10, 1000], [10, 1000] for RGO, SOON, PCSA, and KMAS respectively and with 0.95-confidence intervals illustrated by vertical lines; c² = 1.5. V is measured in μH.
