Examples of detection and matching results between FacetClumps and Dendrograms: The first row shows the matching result of two clumps detected by FacetClumps and one detected by Dendrograms. The left subplot displays the velocity-integrated map of the subregion containing the detected clumps, with the black line marking the boundary of the clump detected by Dendrograms and the red and yellow lines marking the boundaries of the two clumps detected by FacetClumps. The right subplot is similar, except the integration is along the Galactic longitude. The second row shows the matching result of one clump detected by each algorithm, with the rest of the details consistent with the first row.
