16 * @class AliHLTTPCCASliceTrack
17 * AliHLTTPCCASliceTrack class is used to store TPC tracks,
18 * which are reconstructed by the TPCCATracker slice tracker.
fbb9b71b 19 *
63d8b79d 20 * The class contains:
fbb9b71b 21 * - fitted track parameters at its first row, the covariance matrix, \Chi^2, NDF (number of degrees of freedom )
63d8b79d 22 * - n of clusters assigned to the track
23 * - index of its first cluster in corresponding cluster arrays
24 *
25 * The class is used to transport the data between AliHLTTPCCATracker{Component} and AliHLTTPCCAGBMerger{Component}
26 *
