Fig. 4
Position velocity cut along filament F08 in CH3OCHO and H2 CS. The emission to the left corresponds to the filament close to the central hub. The emission at about 0.25 pc and 0.4 pc corresponds to the cores A15 and A08, A19. The white dashed line corresponds to a velocity gradient of ~16 km s−1 pc−1, consistent with the mean velocity gradient of F08 (see Table 2).
