Distribution of the logarithm of the absolute trend (leftmost panel), the frequency of the oscillatory term (second panel) and the logarithm of its relative size, that is, the (uncorrected and corrected) size of the changes ΔA₁ and ΔA_1c divided by Ā₁, the first harmonic amplitude of the average stable-model (third and rightmost panels, respectively), estimated from model (2). Groups and their labels are the same as in Fig. 7.
