Correlation between the [OI]63 μm and [OIII]88 μm summed emission line luminosities, in units of 10⁴¹ erg s⁻¹, and the SFR derived from the total IR luminosity (black dashed line) for a composite sample of SFGs (red stars) and from the Hα luminosity (corrected for the IR luminosity) for LMG (green triangles). Purple squares indicate the sample of ULIRGs included in the SFG sample.
