Difference in DIB parameters (𝒟₈₆₂₁, λ₈₆₂₁, σ₈₆₂₁, and EW₈₆₂₁) between GDR3, AS23, and this work as a function of the fit values for the joint samples. The gray scale indicates the number density of the data points estimated by the Gaussian KDE. The data are binned with a step of 0.005 for 𝒟₈₆₂₁, 0.2 Å for λ₈₆₂₁, 0.1 Å for σ₈₆₂₁, and 0.01 Å for EW₈₆₂₁. The solid red lines in each panel represent the median differences in each bin, and the two dashed red lines show the 16th and 84th percentiles.
