///////////////////////////////////////////////////////////////////////////
// AliITSBadChannelsSPD implementation by P. Nilsson 2005
// AUTHOR/CONTACT: Paul.Nilsson@cern.ch
//
// The class is used by the AliITSPreprocessorSPD class to store the
// final noisy and dead channel objects in the calibration database for
// the SPD.
//
// An instance of this container class contains all the "bad" channels,
// i.e. the noisy or dead channels of the SPD. It contains TObjArrays
// for each module of the SPD (240 in total for ALICE, and 6 for the 2004
// joint ITS beam test. The instance object should, once filled with data,
// be stored in the calibration database. This is done by the SPD
// preprocessor.
