void SiStripNoisesGenerator::fillSubDetParameter ( std::map< int, std::vector< double > > &  mapToFill, const std::vector< double > &  v, const int  subDet, const unsigned short  layers  ) const

private

Fills the map with the paramters for the given subdetector.
Each vector "v" holds the parameters for the layers/rings, if the vector has only one parameter all the layers/rings get that parameter.
The only other possibility is that the number of parameters equals the number of layers, otherwise an exception of type "Configuration" will be thrown.
