33/**
34 * AliHLTMUONRecHitsSource is a HLT-AliRoot data source object which generates
35 * and serves AliHLTMUONRecHitsBlockStruct type data blocks to the HLT system.
36 * This is meant as a debugging utility which can optionally generate the data
159b743b 37 * blocks from simulated GEANT hits or MUON offline reconstructed hits.
38 *
39 * Command line flags:
40 * -simdata
41 * Specify this option to publish GEANT hits.
42 * -recdata
43 * Specify this option to publish offline reconstructed raw clusters.
44 * -plane left|right|all
45 * Specifies if data from the left (x < 0), right (x >= 0) or the whole XY
46 * plane should be published.
47 * -chamber <number>|<number>-<number>[,<number>|<number>-<number>]...
48 * Selects the chambers from which to publish data. Valid chamber numbers
49 * in the range [1..10]. The string after '-chamber' is a comma separated
50 * list of numbers or ranges. Some examples of strings:
51 * 1 1-2 1,2,3 1,3-5,7 etc...
