23 | * AliHLTMUONRecHitsSource is a HLT-AliRoot data source object which generates | |
24 | * and serves AliHLTMUONRecHitsBlockStruct type data blocks to the HLT system. | |
25 | * This is meant as a debugging utility which can optionally generate the data | |
26 | * blocks from simulated GEANT hits or MUON offline reconstructed hits. | |
27 | * | |
28 | * Command line flags: | |
29 | * -simdata | |
30 | * Specify this option to publish GEANT hits. | |
31 | * -recdata | |
32 | * Specify this option to publish offline reconstructed raw clusters. | |
33 | * -plane left|right|all | |
34 | * Specifies if data from the left (x < 0), right (x >= 0) or the whole XY | |
35 | * plane should be published. | |
36 | * -chamber <number>|<number>-<number>[,<number>|<number>-<number>]... | |
37 | * Selects the chambers from which to publish data. Valid chamber numbers | |
38 | * in the range [1..10]. The string after '-chamber' is a comma separated | |
39 | * list of numbers or ranges. Some examples of strings: | |
40 | * 1 1-2 1,2,3 1,3-5,7 etc... | |
