NOTES: 10. Sensitivity is measured at an integration time of 16.667 ms with a source temperature of 2856 K. A CM-500 filter is used.
11. VU is the output voltage that represents the threshold of operation of antiblooming. VU
≈
1/2 saturation signal.
12. Saturation is the condition in which further increase in exposure does not lead to further increase in output signal.
13. Blooming-overload ratio is the ratio of blooming exposure to saturation exposure.
14. Smear is a measure of the 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.
15. Exposure time is 16.67 ms and the fast-dump clocking rate during vertical timing is 2.05 MHz.
16. Dark-signal level is measured from the dummy pixels.
Output signal = 100 mV
