Detailed Description

SIS3320 sampling ADC samples.

Author: W. Deconinck

Date: 2009-09-04 18:06:23

The QwSIS3320_Samples should allow convenient access to the sampling data collected with the SIS3320 for the Compton photon detector. This class implements its own sum, difference, and ratio methods inherited from the general VQwDataElement.
