Relative error on the size of the truncation inferred with SAM with respect to the BT24 measurements as a function of the relative error on the size of the truncation derived from the averaged SAM segmentation maps (ΔR_0.5) split in quintiles. Boxes represent the IQR and whiskers extend from the box to the farthest data point lying within 1.5 × IQR from the box, while the horizontal lines indicate the median value. Median values (and the scatter) of the relative error on the size obtained with SAM compared to BT24 are below the ~5% level for all quintiles with the exception of Q5. For Q5, where the differences between the size of the truncation at 0.5 and 0.7 probability thresholds are the largest, the median value of the relative error on the size of the truncation inferred with SAM surpasses the ~10% level, with a clear increase in the scatter.
