Table 3:

Extreme-UV flux excess factors w as a function of the effective temperature and $\gamma$ , needed to explain the $\Delta T_{\rm eff}^f$ underestimations affecting the $T_{\rm eff}^f$ values for supergiants.
		$w(\gamma)$
$T_{\rm eff}$	$\Delta T_{\rm eff}^f$	$\gamma =1.0$	$\gamma = 1.5$	$\gamma = 2.0$
