Bases:
exosim.tasks.task.TaskComputes the photon noise. Given the incoming signal \(S\) the resulting photon noise variance is \(Var[S]=S\). If photon gain factor \(gain_{phot}\) is given, then \(Var[S]= gain_{phot} \cdot Var[S]\). If photon noise margin \(\chi\) is found in the description, then \(Var[S]= (1+\chi) \cdot Var[S]\). The noise returned is \(\sigma = \sqrt{Var[S]}\)
- Returns:
photon noise
