21 | * @class AliHLTTriggerCosmics | |
22 | * HLT trigger component for charged particle multiplicity in the | |
23 | * central barrel. | |
24 | * | |
25 | * Triggers on charged particle number in a certain pt range and geometrical | |
26 | * acceptance | |
27 | * | |
28 | * Multiple instances of this component can serve different trigger | |
29 | * conditions, i.e. component parameters. The different instances get | |
30 | * different names, specified by the '-triggername' component argument. | |
31 | * The configuration is loaded from OCDB entries according to the name, see | |
32 | * below. | |
33 | * | |
34 | * <h2>General properties:</h2> | |
35 | * | |
36 | * Component ID: \b BarrelMultiplicityTrigger <br> | |
37 | * Library: \b libAliHLTTrigger.so <br> | |
38 | * Input Data Types: kAliHLTDataTypeESDObject, kAliHLTDataTypeESDTree | |
39 | * kAliHLTDataTypeTrack <br> | |
40 | * Output Data Types: ::kAliHLTAnyDataType <br> | |
41 | * | |
42 | * <h2>Mandatory arguments:</h2> | |

49 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |
50 | * \li -mintracks <i> n </i> <br> | |
51 | * required number of tracks for a trigger | |
52 | * \li -minpt <i> pt </i> <br> | |
53 | * required minimum pt for a trigger | |
54 | * \li -maxpt <i> pt </i> <br> | |
55 | * required maximum pt for a trigger | |
56 | * \li -min-ldca <i> dca </i> <br> | |
57 | * minimum longitudinal dca to reference point | |
58 | * \li -max-ldca <i> dca </i> <br> | |
59 | * maximum longitudinal dca to reference point | |

64 | * \li -triggername <i> name </i> <br> | |
65 | * The name of this specific trigger. | |
66 | * | |
67 | * By default, configuration is loaded from OCDB, can be overridden by | |
68 | * component arguments. | |
