Varying the flux (but not the spectrum) from an X-ray set by varying the tube current, for three different calibrations of pixel (7,7). As the fine count to kiloelectronvolts conversion is now series-dependent, the approximate fluxes corresponding to ∼200 photons per pixel per frame and ∼900 photons per pixel per frame are shown as vertical lines instead. Data points with a cross marker were not included in the linear fit. The coarse counter limit is at (28 − 1) × 64F (fine counts).
