Fig. 4

Scatter plot representing the bootstrapping results for the median difference between the mass relative errors in the original and recalibrated datasets. Each dataset is characterized by its \(\stackrel{\sim }{\Delta }\) value (calculated following the method described in Additional file 1: Section S6) and the significance value of the bootstrapping test. Most datasets show a significant reduction of the test masses absolute error, with values up to about 60 ppm
