Histograms of the relative difference and absolute value of the relative difference in D and T ₁ parameter estimates. Median values are represented with a vertical black line, while a pink highlighted block is used to represent the 5%–95% quantile range. Top left: relative difference in diameter. Top right: relative difference in pseudo-temperature T ₁. Bottom left: absolute value of relative difference in diameter. Bottom right: absolute value of relative difference in pseudo-temperature T ₁.
