Paper Abstract

Electron Multiplying CCD is a CCD technology sensor reduces read-out noise to less than one electron. We study the way the usage of this technology affects to the astronomical photometry and to the improvement of the temporal resolution of the measurements. We show the effect of this technology on individual celestial sources and in the limiting magnitude. We propose a criterion to choose the optimal EM gain for a specific integration time. We explain a straightforward procedure to characterize the actual EM gain and the readout noise expressed in photo-electrons for every software-displayed gain, and we applied this procedure to the Andor Ixon DU-888E-C00-BV EMCCD.
