SOFIA/FIFI-LS [C II] spectra (black lines) for each object integrated within 36″ diameter apertures. The CO(1–0) and best-fit Gaussian or double-Gaussian profiles are shown as red dashed and solid green lines, respectively. The CO(1–0) and [O III]5007 Å line profiles of the HE 1353−1917 outflow are shown as orange dashed and dotted lines. The comparison line profiles are degraded to the spectral resolution of SOFIA. The atmospheric transmission curves are shown in blue, and the shaded regions of low transmission are excluded from the analysis.
