// Class  for bad channel treatment in the tracker                 //
// Stores 1 status bit for each SPD pixel and SDD anode:           //
//  0 = bad channel                                                //
//  1 = good channel                                               //
// Dead and noisy channels are read from AliITSCalibration objects //
