///////////////////////////////////////////////////////////////////////////////
//
// HMdcCalibrater2Sim
//
// This transformation class is used for simulated data and is derived from
// the transformation class HMdcCalibrater2 which calculates the distances to
// the wires from the Cal1 drift times.
// The additional information for simulated data (track numbers, cell status,
// tracklist, statuslist)
// is copied in the overloaded calibrate function.
