Fast fitting of spectral lines with Gaussian and hyperfine structure models

Open Access

Fig. 5

Examples of synthetic N₂H⁺ spectra (solid black lines) and the fitted hyperfine profiles (dashed red lines). The spectra are for direction x, R = 8, and without added observational noise. The y-axis of each frame was scaled independently, and the shown T_A axis values apply to the leftmost frames only.
