a The read-ou noise (RON) in the default Non-Destructive Read (NDR) mode depends on the DIT: the detector is read continuously every 1.3 s, i.e. the longer the DIT, the more reads are possible and the lower the RON. For the minimum DIT (1.3 s), the RON is 12 e-; for DIT = 10 s, the RON is 8 e- and for DIT > 15 s, the RON remains stable at 5 e-.
