PoissonianGaussianNoise

trait PoissonianGaussianNoise:
    .doc: """
    Trait for adding Poissionian-Gaussian noise, as described by Foi et al. in
    'Practical Poissonian-Gaussian noise modeling and fitting for single-image
    raw-data', to a digital camera sensor.

    The quantum efficiency denotes how efficient the photon-to-charge transfer
    in each bin is, whereas the pedestal parameter configures the base charge
    of each bin and the gain noise factor relates the analog gain to the sensor
    ISO amplification.
