4. The array is uniformly illuminated with a diffused LED source having a peak wavelength of 640 nm.
5. PRNU is the maximum difference between the voltage from any single pixel and the average output voltage from all pixels of the
device under test when the array is uniformly illuminated at the white irradiance level. PRNU includes DSNU.
6. Nonlinearity is defined as the maximum deviation from a best-fit straight line over the dark-to-white irradiance levels, as a percent
of analog output voltage (white).
7. RMS noise is the standard deviation of a single-pixel output under constant illumination as observed over a 5-second period.

10. DSNU is the difference between the maximum and minimum output voltage for all pixels in the absence of illumination.
11. Image lag is a residual signal left in a pixel from a previous exposure. It is defined as a percent of white-level signal remaining after
a pixel is exposed to a white condition followed by a dark condition:
