Distributions of #x0394;m₁₅ light curve width parameter (top) and color excess at peak E(B − V) (bottom) of the calibrator (in orange) and Hubble-flow (in green) SN Ia samples obtained from SNooPY fitting UV, optical, and NIR light curves simultaneously with the EBV_model2. Vertical dashed lines represent the average value of the distributions. The p-value of the two-sample K–S test is included in each panel.
