Spectra of CO(1–0) and Hα emission in Haro 11. Left: CO(1–0) spectra collected from the knots (A, B, C, T), the region (r ∼ 0.6″, marked as B/C) between B and C, and the entire CO region. Right: Hα spectra collected from the knots (A, B, C, T), the region between B and C marked B/C, and the R₈₀ region. The dash-dotted lines show the rest-frame wavelength of the Hα emission line. In each panel, blue lines represent the best one-Gaussian fitting spectra, attached with the relevant results, for example, the velocity of CO and systemic velocity subtracted velocity of Hα. The velocity dispersion σ values are derived from the Gaussian widths by subtracting the instrument resolution. Dashed lines represent the fitting velocity of CO and Hα.
