-Service for providing silicon properties for each detector element.
+Tool for providing silicon properties for each detector element.
 The properties are available via the SiliconProperties class from
 which one can obtain hall and drift mobility, diffusion constant and
 number of electron hole pairs per deposited energy.  Some of these
 are dependent on temperature and voltages which are obtained via the
-appropriate service and updated via a call back.
