/**
 * @file cal-hlt-tpc-offline.C
 * @brief Test macro for the HLT TPC offline calibration.
 *
 * The macro runs an HLT chain of TPC analysis, using the offline
 * algorithms and appropriate wrappers. The final output is
 * processed by the TPCOfflineCalibration component.
 *
 * Usage:
 * <pre>
 *   aliroot -b -q cal-hlt-tpc-offline.C | tee cal-hlt-tpc-offline.log
 * </pre>
 *
 * The chain to be run is defined by the macro given to the parameter
 * 'config='
 *
 * The macro asumes raw data to be available in the rawx folders, either
 * simulated or real data. A different input can be specified as parameter
 * <pre>
 *   aliroot -b -q cal-hlt-tpc-offline.C'("input.root")'
 * </pre>
 *
 * In the first section, an analysis chain is defined. The scale of the
 * chain can be defined by choosing the range of sectors and partitions.
 *
 * The reconstruction is steered by the AliReconstruction object in the
 * usual way.
 *
