NOTES:
2. DSNU is the difference between the highest value pixel and the lowest value pixel of the device under test when the array is not
illuminated.
3. PRNU does not include DSNU.
4. PRNU is the difference between the highest value pixel and the lowest value pixel of the device under test when the array is uniformly
illuminated at nominal white level (typical average output level = 200).
