10 * @struct AliHLTTPCDigitData
11 * Raw data structure for one row of TPC data. A digit corresponds to one
12 * measured signal in 2 coordinates: pad and time <br>
13 * The hight of the signal is given by the charge. <br>
14 * This structure is only used while runnig HLT analysis in the offline
15 * framework. Thats why it comes with a MC track id by default.
16 *
17 * The exact meaning of the 3 track ID fields is currently not known to me.
