Ratios of [C II] over far-IR emission as a function of the infrared surface brightness
Ratios of [C II]
Date

Ratios of [C II] over far-IR emission as a function of the infrared surface brightness. The blue symbols depict observations from a comparison sample (Diaz–Santos et al. 2017) and the shaded band is the fitted curve with 1-σ uncertainty showing the zone where the [C II] emission is compatible with star formation. The black and red symbols represent the data for the northern and southern counter-arm regions, respectively.
