Linear coefficients for detector pixel mean with different detector gain modes. Linear fitting slope g and intercept p measured using the cylinder object are shown for two different detector modes: (g_dyn,p_dyn) for dynamic gain and (g_low,p_low) for fixed low gain. For dynamic gain mode, the detector elements outside of the gain switching edges switched from fixed high gain mode to fixed low gain mode (with the 15th bit set to “1”) during the incremental exposure measurement. Thus, the linear fitting coefficients have a very large fluctuation. Pixels located between #150 and #850 were using a higher gain from the dynamic gain for all the exposure levels. These data show that p does not have a strong dependence on the detector mode.
