Note 1 : Pixel saturation (full well) as a function of vertical transfer frequency (see figure 12) and antiblooming
Note 1 : adjustment (see figure13).
Note 2 : After subtraction of dark signal slope due to memory readout time
Note 3 : First line level referenced from inactive prescan elements (12 samples)
Note 4 : Last line level referenced from inactive prescan elements (12 samples)
Note 5 : Measured with Correlated Double Sampling (CDS) including 160 µV readout noise and dark current noise
Note 5 : in the general test conditions.
Note 6 : Saturation to RMS noise in darkness ratio.
Note 7 : At Nyquist frequency.
Note 8 : VSAT / 2 measurement and 1.25 MHz vertical transfer frequency.
