Bootstraps distribution of the $L_X^{0.5-2}$ as a function of the SFR and the sSFR. The left panel shows the distribution of the SFR-M_⋆-D stacks in the $L_X^{0.5-2}$-SFR plane. Red line depicts the standard scaling relation from Mineo et al. (2014) (M14). The right panel shows the same distribution in the $L_X^{0.5-2}$/SFR – sSFR plane and the red line the scaling relation from Lehmer et al. (2016) (L16). Cyan error bars correspond to the 90% C.I. of the X-ray luminosity based on a bootstrap sampling. Black stars show the secure star-forming galaxies with reliable flux measurements with their corresponding uncertainties, and the grey down-arrows the galaxies with uncertain flux measurements.
