Hierarchical fragmentation. Grayscale shows the primary beam uncorrected 7 m + 12 m combined images, overlaid with primary beam uncorrected 7 m ACA continuum in black (positive) and green (negative) contours with levels of ± 7 m image 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 yellow contours show the “leaves” and their shapes derived by Astrodendro. Large and small triangles mark the positions of candidate ensembles and cores, respectively. Green and red lines are MST core separations the same as those in Figs. 3 and 4. Blue lines indicate the clump thermal Jeans length, .
