// BrDcCalibration is a BRAHMS data class providing storage and 
// access function for Drift Chamber specific calibration parameters.
// Note that all the DB access work is done in the Baseclass. The user
// code tells the Baseclass the name and element of the data
// 
// Code inspired by BrTofCalibration.cxx
