+     - implemented a new treatment of "no-signal". If a pixel
+       presumably contains no signal as detected by the arrival time
+       interpolation its interpolated signal is overwritten with
+       a gaus. The gaus mean and rms are taken from the corresponding
+       MPedPhotCams

+   - callisto: In addition to the new treatment of arrival times the
+     decision of the treatment whether a pixel contains shower
+     information or not is used to improve the signal interpolation
+     further. Previously interpolated pixels showed a non-zero signal
+     do the peak searching signal extractors. Having a signal pixel
+     beside raised the signal above the cleaning level. Thus the
+     pixel survived cleaning to often but with a too low mean signal.
+     By replacing empty pixels with a gaus (mean and rms from the
+     corresponding Area entries in MPedPhotCam) this effect can
+     be supressed.
