Notes:
1. Value measured with respect to zero reference level (see Figure 1).
2. Conversion factor is typically 1.1 µV/e-.
3. ∆R/R is defined as
2_----0_---0_-----R_----A_{-----–-----}R_----B_----
RA + RB
where RA is responsivity of video output A
RB is responsivity of video output B
4. Measured in Correlated Double Sampling (C.D.S.) mode.
