Histograms of the relative error in absolute value of the prediction of CME masses for the 32 events using Eq. (3). Left: absolute value of the relative errors of the CME mass estimation using the parameters from the fitting functions for the uncorrected case (Col. 16 of Table 1). Right: same for the corrected case (Col. 18 of Table 1). The vertical dotted lines indicate the 50th, 75th, and 90th percentiles.
