NOTES: 9. Sensitivity is measured at an integration time of 33 ms with a source temperature of 2859 K. A CM-500 filter is used. Sensitivity is
measured at any illumination level that gives an output voltage level less than VU.
10. VU is the output voltage that represents the threshold of operation of antiblooming. VU ≈ 1/2 saturation signal.
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 the measure of error induced by transferring charge through an illuminated pixel in shutterless operation. It is equivalent
to the ratio of the single-pixel transfer time during a fast dump to the exposure time using an illuminated section that is 1/10 of the
image area vertical height with recommended clock frequencies. Exposure time is 33 ms, the fast dump clocking rate during vertical
timing is 1 MHz, and the illuminated section is 1/10 of the height of the image section.
14. Dark-signal level is measured from the dark dummy pixels.
