-for 
-one typical inner pixel and one typical outer pixel and a non-saturating calibration pulse of UV-light, 
-obtained with three different extractors. One can see that the first two yield a Gaussian distribution 
-to a good approximation, whereas the third extractor shows a three-peak structure and cannot be fitted. 
-We discarded that particular extractor for this reason.

+for a typical inner pixel and a non-saturating calibration pulse of UV-light,

+except for the sliding window extracting 2 slices which shows a three-peak structure and cannot be fitted. 
+We discarded that particular extractor for the further studies.
