The temperature bias in the simulated spectra as a function of the fraction of the linear bias in the effective area at 10 keV for the 2.0−7.0 keV band fits (dotted lines) and for the  ~ 6−7 keV band fit (dashed lines). The different dotted lines denote different input temperatures from 4 to 10 keV (higher temperatures yield higher bias). For the  ~ 6−7 keV band fit only the curves for kT = 10 keV are shown for clarity. The lines in the upper half (lower half) correspond to positive (negative) bias in the effective area.
