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
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...
52 : * -firstevent <number>
53 : * Indicates the first event number to fetch from AliRoot. The default is to
54 : * start from zero and increment the event number after every GetEvent call.
55 : * This mode causes the component to ignore the event number passed to it by
56 : * the system and rather use an internal counter. This mode can be overriden
57 : * with the -event_number_literal flag.
58 : * -event_number_literal
59 : * This flag indicates to use the event numbers as literal indices into the
60 : * AliRoot trees. This option will cause the component to ignore the -firstevent
61 : * flag.
