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 | |
