Gas heating efficiency proxy, ([CII] + [OI])/TIR, as a function of the dust temperature (blue (east) and red (west) dots). For comparison, the results from Beirão et al. (2012) in the circumnuclear star forming ring of NGC 1097 (“x”), and Croxall et al. (2012) in sub-kpc regions in NGC 1097 and NGC 4559 (dashed line) are indicated. The [CII] has been corrected for its 10% diffuse ionized component.
