Example spectra of the [C II] 157 μm line for two different positions in IC 59. The data is shown in black, while the Gaussian line profile fit is shown in red. The blue dashed lines indicate ±2σ of the continuum level. Right panel: spectrum at the position (RA, Dec) = (00:57:37, +61:08:07) at the northern part of the map shown in Fig. 9, left panel: corresponds to a position in the southern part of the map, at (RA, Dec) = (00:57:39, +61:06:28).
