{synonym}

<Detector conversion gain> is the number of collected <Electrons> per <analogue-to-digital unit>. With independent <Poisson distribution> photoelectron counts, the shot-noise <variance> in count units is the mean count divided by the gain. Detected-photon and <Electron> conventions agree only when each detected <photon> contributes one <Electron>.
