First three plots show the results for the error renormalisation analysis for G, G_BP, and G_RP respectively. The errors are all in magnitudes. In these plots, the median quoted error is shown along with the additional error from this analysis. We note that the BP and RP plots have a larger ordinate axis maximum. The final plot shows the additional error for all three passbands at the same time to aid comparison. Missing points indicate where the algorithm has failed.
