7 m ACA continuum images uncorrected for primary beam. ATLASGAL 870 μm emission is shown with black contours with levels the same as Fig. 1. Red (positive) and green (negative) contours show the 7 m ACA emission with levels of ± rms × [3, 3^1.25, 3^1.50, 3^1.75, 3^2.0, 3^2.25, 3^2.50, 3^2.75, 3^3.0]. Blue ellipses and orange contours indicate the leaves and their pixels derived by Astrodendro, respectively. The red numbers mark the ranking of leaves’ mass in Table A.3.
