6.2.3.3 Final noised pixel value ¶

Based on the discussions in Photon counting noise and Instrumental noise, depending on the values you specify for $B$ and $C$ from the above, the final noised value for each pixel is a random value chosen from a Gaussian distribution with

$$\mu=B+I_{nn}, \quad \sigma=\sqrt{C^2+B+I_{nn}}$$
