Four representative individual-pixel spectra of the cataloged H I sources, together with the Gaussian fitting results. Only Gaussian components above threshold = 2 are shown. The original spectra are shown in black, with the best-fit in orange and independent Gaussian components in cyan, purple, and green. All spectra are fitted using the ROHSA model with N = 3. In the bottom row, the left panel shows an example that satisfies the adopted merging criteria, whereas the right panel shows an example that does not satisfy the merging criteria.
