00008  * Description : This ThPair is used in ThCFGaussFit. it Inherit from 
00009  * ThPairGauss. functionality are add to save the position of emission in 
00010  * the gaussian distribution before the lorentz Transformation. Then
00011  * the method GetRejectionProb2Size(x,y,z,t) return the rejection probability 
00012  * that must be applied so that the effective distribution is a gaussian with
00013  * size x,y,z,t
