Table 2.

Slope, intercept, and dispersion values for the SFR (and L_IR in parentheses) vs. $L'_{[CI] ((1 - 0)}$ $\rm L{\prime}_{[CI]((1-0)}$ and $L'_{CO ((1 - 0)}$ $\rm L{\prime}_{CO((1-0)}$ relations.

Model		$L'_{[CI] ((1 - 0)}$ $\rm L{\prime}_{[CI]((1-0)}$ [K km s⁻¹ pc²]			$L'_{CO ((1 - 0)}$ $\rm L{\prime}_{CO((1-0)}$ [K km s⁻¹ pc²]

lmfit	1.06 ± 0.02	−7.76 ± 0.22	1.98 ± 0.21	1.24 ± 0.02	−10.39 ± 0.24	−0.63 ± 0.23	0.42 dex

Notes. Intercept values are given separately for the SFR and the IR luminosity (see Eqs. (7) and (8)). The dispersion values are the same regardless of the tracer.
