NOTES: 10. Theoretical value
11. Saturation is the condition in which further increase in exposure does not lead to further increase in output signal.
12. Blooming is the condition in which charge is induced in an element by light incident on another element. Blooming-overload ratio
is the ratio of blooming exposure to saturation exposure.
13. Smear is a measure of the error introduced by transferring charge through an illuminated pixel in shutterless operation. It is equivalent
to the ratio of the single-pixel transfer time to the exposure time using an illuminated section that is 1/10 of the image-area vertical
height with recommended clock frequencies.
14. The exposure time is 16.67 ms, the fast-dump clocking rate during vertical transfer is 12.5 MHz, and the illuminated section is 1/10
the height of the image section.
