+The pulse shape is mainly determined by the artificial pulse stretching by about 6\,ns on the receiver board. 
+Thus the first assumption holds to a good approximation for all pulses with intrinsic signal widths much smaller than 
+the shaping constant. Also the second assumption is fulfilled: Signal and noise are independent 
 and the measured pulse is the linear superposition of the signal and noise. The validity of the third 
 assumption is discussed below, especially for different night sky background conditions.
