Correlation between pull values for all parameters for ML_w/z (red) and ML_wo/z (blue). The quality of reconstruction, represented by the mean pull value, is more correlated between the variables in ML_wo/z than it is for ML_w/z. The vertical dashed lines in the histograms indicate the 0.16 and 0.84 quantites of the distributions, and the numbers show the respective medians and 0.16 and 0.84 quantites.
