[C II]158 μm fine structure lines of LARS galaxies. Herschel/PACS spectra are shown in the top row, and SOFIA/FIFI-LS spectra in the bottom row. Total fluxes were derived using Gaussian fits (see Table 6). For FIFI-LS data, the atmospheric absorption, calculated using ATRAN (Lord 1992), is shown as a red curve. Spectral ranges with strong atmospheric absorption (see orange range) were masked out for the fitting process. The zero-velocity (red vertical line) is related to the H I systemic velocity from Pardy et al. (2014) for all LARS galaxies but LARS 12−14 (which have no H I detection). For those, the systemic velocity is based on SDSS optical redshifts.
