Spectra of the ¹³CO (black) and C¹⁸O (red) lines. These spectra were extracted along skeleton of the Filament 1. The green solid lines correspond to the Gaussian fits listed in Table B.6. The blue dashed line shows the velocity of 10 km s⁻¹. The corresponding positions for each spectra are indicated in the top left corner of the panels. The positions corresponding to the filaments outside the hub are labeled in black. The positions corresponding to spectra inside the central hub (R_hub = 250″) are in blue. The colored symbols in the panels indicate the positions corresponding with sources identified by Rayner et al. (2017). The pink stars correspond to protostars, the green circles to bound cores, and the red triangles to unbound clumps. The large aqua circles correspond to the sources identified by Sokol et al. (2019). Figures B.5–B.12 show the spectra along the Filaments 2–9 skeleton. Figures B.13 and B.14 show the spectra along the secondary filament skeletons.
