Spectra of [¹³C II], [¹²C II], and [O I] at selected positions in the LMC. Left: [¹²C II] spectra (blue) and [O I] 63 μm spectra when available (green). The vertical lines aid the comparison of the velocities of the line profiles. Middle two panels: [¹³C II] F = 1−0 and F = 1−1 spectra (red) and [C II] spectra (blue) scaled for optically thin emission and ¹²C⁺/¹³C⁺ = 49. The horizontal lines indicate the rms noise of the baseline. Right: combined [¹³C II] spectra (red) and the scaled [C II] spectra (blue). See text for the formula of the combined [¹³C II] spectra and the scaled [C II] spectra.
