Month = 1 corresponds to January. The amplitude is the difference between the higher and lower points in mm.month−1 of the sinusoid fitted in the cosinor analysis. The phase and the low phase are, respectively, the month with the highest/lowest tree growth value according to the sinusoid fitted in the cosinor analysis. A 
indicates that the statistically significant existence of a seasonal pattern cannot be rejected.
