They were taken from the tip of the bottom leaf to the tip of the bottom leaf in the case of Ravello and to the top leaf below the red line (Fig. 5) to ensure comparability. Manual measuring error is ± 0,2 mm to calculate the error propagation, which led to a relative propagated error of ± 0.1% in all cases.
