Comparison of the different extinction references considered in this work: Vergely et al. (2022), Edenhofer et al. (2024), Bayestar19, and gspphot. Each panel shows a 2D histogram of the extinction comparison between two references. The color bars indicate logarithmic density (with the same range for all panels), and the 1:1 line is shown in magenta. The number of stars in each plot is indicated in the bottom-right corner. Given that the Bayestar19 values are reported to fewer decimal places than the other references, the panels involving this map display horizontal/vertical stripes. The gspphot extinctions show the largest disagreement of all the references. For the CMD analysis, we adopted the Vergely et al. (2022) map as the source of extinctions.
