Energy and efficiency calibration

We make calibrations for the remaining D4 CLOVER detector
(No pulser: D4 preamp does not see the pulser input, a single TEST input)

The threshold in Black,Green and Blue is cutting Ba X-rays.

Activity of the sources:
>> 60Co (Ref:CD395): 338.4 kBq (+-3%) measured on 01.07.1990
>> 137Cs (Ref:CD393): 347.9 kBq (+-3%) measured on 01.07.1990
>> 152Eu (Ref:272/09-7011): 10.62 kBq (+-1,9%) measured on 16.03.2010
