Screenshot of the ppv distribution of the four main trees identified by ACORNS, shown with distinct colors (A: red, B: blue, C: green, G: purple). The color scale within each tree is determined by the peak intensity of the N₂H⁺ component. The black dots show the ppv position of the H₂D⁺ cores (taken at the peak of the line integrated intensity), while the magenta diamonds represent the positions of the protostellar cores, following Li et al. (2020). A permanent copy of this interactive plot is available at: http://theory-starformation-group.cl/sbovino/AG14_n2hp_light.html. The interactive version allows the reader to rotate the figure, to zoom in and out, and to see the numeric labels of the protostellar and prestellar cores by moving the cursor over.

An interactive version of this figure is available in the online journal.
