Fig. 4From: A step-by-step evaluation of empirical methods to quantify eruption source parameters from tephra-fall depositsSensitivity analysis of the distal integration limit of the power–law method on the final volume/mass. The left y–axis shows the absolute values of volume/mass as a function of C, whereas the right y–axis shows the discrepancy (%) relative to the user–specified value of CBack to article page
