(1) Light source temperature is 2856 °K. The IR filter used is CM500 1 mm thick.
(2) Saturation is the condition in which further increase in exposure does not lead to further increases in output signal.
(3) Zero input offset is the residual output signal measured from the reset level with no input charge present. This level is not caused by the
dark current and remains approximately constant independent of temperature. It may vary with the amplitude of SRG1.
(4) Blooming is the condition in which charge induced by light in one element spills over to the neighboring elements.
(5) Smear is the measure of error signal introduced into the pixels by transferring them through the illuminated region into the memory. The
illuminated region is 1/10 of the image area height. The value in the table is obtained for the integration time of 33.3 ms and 1.5 MHz
vertical clock transfer frequency.
(6) Dark current depends on temperature and approximately doubles every 8 Co. Dark current is also multiplied by CCM operation. The
value given in the table is with the multiplier turned off and it is a calculated value.
(7) Dark signal is actual device output measured in dark.
