Improvement in the fitting of the spectra using multi-Gaussian methods. Top panel: comparison between the single-Gaussian (light blue) and the double-Gaussian (pink) methods used to fit the intensity peaks of C₂H at 50 au. Bottom panel: same as top panel, but for the three hyperfine components of the HCN transition.
