This figure shows the H¹³CO⁺ spectra, with Gaussian fitting results shown only at positions 1, 6, 9, 13, and 20. Black curves represent the H¹³CO⁺ spectra extracted from positions in Figure 2. The vertical dashed gray line marks the central velocity of Cloud H (45.5 km ⁻¹). The corresponding green numbers (see Figure 2) are displayed at the top left corner of each panel. Other symbols are the same as in Figure A.2.
