29 * @class AliHLTTPCClusterFinderComponent
30 * Implementation of the cluster finder component.
31 * The component implements the interface methods of the @ref AliHLTProcessor.
32 * The actual cluster finding algorithm is implemented in @ref AliHLTTPCClusterFinder.
de554e07 33 * The component can handle unpacked and packed data of different formats via the
34 * AliHLTTPCDigitReader implementations. Two components are registered, the
35 * TPCClusterFinderUnpacked and the TPCClusterFinderPacked. The latter one can
36 * instantiate different digit readers depending on the arguments.
84645eb0 37 *
38 * The component has the following component arguments:
01f43166 39 * - rawreadermode the mode for the @ref AliHLTTPCDigitReaderRaw, use -2 if using unsorted
84645eb0 40 * - adc-threshold ADC count threshold for zero suppression, if <0 the base line
41 * calculation and subtraction is switched off
42 * - pp-run set parameters specific to a pp run; currently this switches
01f43166 43 * cluster deconvolution off for pp runs (not true for unsorted reading)
44 * - unsorted if 1 the data will be read unsorted in to a PadArray object. This should
45 * only be done on patch level since it use a lot of memory
46 * - patch specify on which patch to resd the data unsorted
