Relationships between Σ_SFR and [NII] 205 μm (red dots), between Σ_SFR and [CI] 370 μm (green squares), and between Σ_SFR and I_CO(1−0) (black triangles). The sizes of the red dots and green squares are proportional to the S/N of the measured intensities. For [NII] 205 μm, the S/N ranges between 0.3 and 10.0 with a median value of 2.4. For [CI] 370 μm, the S/N ranges between 0.1 and 10.0 with a median value of 2.3. [NII] 205 μm and I_CO(1−0) are compared with Σ_SFR at a spatial resolution of 22′′, and [CI] 370 μm is compared with Σ_SFR at a spatial resolution of 38′′. The red and black dashed lines indicate the SFR calibration converted from that given by Zhao et al. (2013) for [NII] 205 μm and by Kennicutt et al. (2007) for I_CO(1−0), respectively. The box in the bottom right shows the integrated quantities of SFR and L_{[NII] 205 μm} of M 83 from this work, with the dynamical range of both axes set to be the same as that in Zhao et al. (2013, Fig. 2).
