Figure 2 shows the pixel response curve in linear response
mode. This curve is the relation between the electrons
detected in the pixel and the output signal. The resulting
voltage-electron curve is independent of any parameters. The
voltage to electrons conversion gain is 13.5 µV/electron.
Note that the upper part of the curve (near saturation) is
actually a logarithmic response.
