+     - Change in line 204:    if ((*fBadPixels)[i].IsBad()) by
+       if ((*fBadPixels)[j].IsBad())   The way it was done, it never
+       worked, because the check on whether the neighbour pixels
+       were OK was performed on the same pixel to be treated (i), which 
+       is obviously not OK. The same problem fixed in the interpolation 
+       of pedestals. Amazingly, this error would have shown up in any
+       test of the class.... I assume it must have been commited 
+       completely untested.
+
+     - In InterpolateSignal: moved division of summed charge over 
+       number of pixels : put it after the check of the number of 
+       valid neighbours to avoid division by 0.
