- their source; skyglow (light pollution) photons, dark current electrons, and photons from the stars themselves exhibit this shot noise superimposed on the actual count of the number of events from that source. When we talk about these sources of signal in our photometry systems, this Guide will be careful to distinguish between the level of the signal and the amount of noise superimposed on the signal. · aavso.org
