Left: Fs and IFs overlaid on the H₂ column density map obtained from Herschel data (P. Didelon et al. 2015; M. S. N. Kumar et al. 2022). The filled contours indicate individual regions identified as C¹⁸O velocity-coherent structures tracing the Fs. The nonfilled contours correspond to the regions identified as ¹³CO velocity-coherent structures tracing the IFs. The two dotted lines indicate the radial distances of 0.8 pc and 1.8 pc from the magenta star, indicating IRS 1, corresponding to the size of hub and the radial extent analyzed in this work, respectively. The scale bar and beam size of 21﹩\mathop{.}\limits^{\unicode{x02033}}﹩8 are shown in the bottom right corner. The green cross indicates the position of the prestellar core with a mass of 2.2 M_⊙ identified using Herschel data by T. S. M. Rayner et al. (2017). Right: centroid velocities of ¹³CO components within each contour as a function of the radial distance from the central star shown in the left panel. The names of each contour region are labeled in the top left corner. The green and gray lines show the positions of the prestellar core and the 1.8 pc radial distance from IRS 1.
