Comparison of molecular cloud distances derived using three independent methods in this work: the statistical method based on extinction–distance distribution differences (D_KStest), the morphological-matching method (D_Kmeans), and correlation analysis of distance-sliced dust maps (D_Correlation). The top and bottom rows show pairwise comparisons and their corresponding difference plots, respectively: (a), (d) D_KStest versus D_Kmeans; (b), (e) D_Correlation versus D_KStest; and (c), (f) D_Correlation versus D_Kmeans. In all panels, molecular clouds with distances available from three methods are highlighted in yellow. The dashed lines indicate the one-to-one relation (top row) and the zero-difference line (bottom row).
