The relative bias of the temperature derived by fitting the simulated spectra in the 6.45−7.25 keV band as a function of the number of counts for the input values kT = 5−7 keV (dotted blue lines) and for kT = 8−10 keV (solid lines). The dash-dot line shows the allowed upper limit of 2% for the bias in the sample.
