The gain of an EMCCD system varies with temperature. The graph below shows
how the gain multiplication increases as the temperature decreases. Curves are shown
for various software gain settings and the figures are typical values. So if a system is
operated at room temperature it will have reduced gain. Because of this temperature
dependence it is recommended that the system is cooled, so that the temperature, and
hence the gain, is stabilized.
