class AliHLTTPCConfMapper;
* @class AliHLTTPCSliceTrackerComponent
* The TPC conformal mapping tracker component.
*
- * The component has the following component arguments:
- * - disable-merger disable merging of track segments
- * - pp-run parameter set for pp run
- * - multiplicity multiplicity to choose parameter set for
- * - bfield magnatic field
+ * Component ID: \b TPCSliceTracker <br>
+ * Library: \b libAliHLTTPC.
+ *
+ * Mandatory arguments: <br>
+ * \li -bfield <i> magnetic field </i> <br>
+ * should allways be used. If there is no magnetic field, use 0.00001
*
- * @ingroup alihlt_tpc
+ * Optional arguments: <br>
+ * \li -pp-run <br>
+ * will give fixed trackparameters for p-p runs.
+ * \li -Pb-Pb-run <br>
+ * will give fixed trackparameters for Pb-Pb runs.
+ * \li -multiplicity <i> multiplicity </i> <br>
+ * set the multiplicity of your collitions. Used for Pb-Pb events.
+ * \li -disable-merger <br>
+ * turns off the intermerging on sectorlevel. Only use in spacial cases.
+ * \li -nonvertextracking <br>
+ * the tracking will do a reconstruction of clusters without vertex constraint.
+ * \li -mainvertextrackingoff <br>
+ * will turn off the tracking with vertex constraint. Use together with -nonvertextracking.
+ * \li -etarange <i> eta range </i> <br>
+ * sets the eta range for the tracking.
+ * \li -etasegment <i> eta segments </i> <br>
+ * let you set the number of eta segments in the trscker.
+ * \li -chi2cut <i> chi² </i> <br>
+ * set the chi² for the tracker.
+ * \li -rowscopetracklet <i> number of padrows </i> <br>
+ * tells the tracker how many padrows down it should look for the next cluster when making tracklets.
+ * \li -rowscopetrack <i> number of padrows </i> <br>
+ * tells the tracker how many padrows down it should look for the next cluster when making track.
+ * \li -trackletlength <i> number of clusters </i> <br>
+ * the minimum number of clusters to be on a tracklet.
+ * \li -tracklength <i> number of clusters </i> <br>
+ * the minimum number of clusters to be on a track.
+ *
+ * @ingroup alihlt_tpc_components
