Same as Figure A.4, but for the southern region containing clump F1 and F2. The 3 mm continuum peaks of clump F2 are indicated as orange crosses and linked with lines to indicate the filament ridge. Contour levels start from 0.4 K km s⁻¹ to the peak integrated intensities of the [88, 93] km s⁻¹ range with eight uniform intervals. The peak integrated intensities are 11.3, 4.8, 2.8, 2.6 K km s^-1 for CS (2–1), SO (2₃–1₂), H¹³CO⁺ (1–0), and HC₃N (9–8), respectively. Integrated intensity maps of certain velocity range for some lines are trimmed if the emission is not significant.
