Examples of 13CO spectra extracted from the same positions as in Fig. 6 and the Gaussian fitting results if available. The 13CO spectra are shown in thick black lines. The HISA spectra from the same locations are scaled to 1/25 of its original intensity and shown in thin blue lines. The positions corresponding to each spectrum are shown in Fig. 1. For Spectra 1, 4, and 5, we can fit the spectrum with a Gaussian component to the 13CO spectrum successfully, we show the Gaussian fitting result with a black solid curve in each panel. For Spectra 2 and 3, the Gaussian fitting results did not meet the criteria we described in Sect. 3.1 and were ignored.
