Distribution of the L_X^{0.5 − 2} as a function of the SFR and the sSFR. The left panel shows the distribution of all the HEC-eR1 secure star-forming galaxies 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 corresponding scaling relation from Lehmer et al. (2016) (L16). Black stars show the secure star-forming galaxies with reliable flux measurements with their corresponding uncertainties (Table B.1), and the grey down-arrows the galaxies with uncertain flux measurements.
