Derived CH₃OH column density (E-type) and hydrogen volume density distribution from RADEX modelling for clumps MM2, MM3, and C (upper panel). One-component Gaussian fit result of CH₃OH (2–1) line series (lower panel). The centroid velocity (with respect to V_LSR = 91.7 km s^–1) and velocity dispersion (σ_v = ΔV/2.355) distribution. In left panels, the contours represent integrated intensity levels of CH₃OH E-type 2(0,1)–1(0,1) line. The velocity range for integration is 85–100 km s^–1, and the contour levels are from 1.3 K km s^–1 (7 σ) to 37 K km s^–1 (0.75 times peak emission value of MM2) with seven uniform intervals. In right panels, the gray contours represent the 3 mm continuum emission, and are logarithmically spaced from 2σ_v (σ_v = 1.6 mJy beam^–1) to 225.0 mJy beam^–1 with five intervals (same as Fig. 2). Cyan crosses mark the 3 mm continuum peak of MM2 and MM3. The green contours indicate n(H₂) levels of 10^6.1 cm^–3 and 10⁷ cm^–3.
