/**
* @class AliHLTTriggerPhosMip
* HLT trigger component for Minimum Ionizing Particles (MIPs) in PHOS.
*
* Triggers on PHOS clusters containing total energy in the range
* fEMin < energy < fEMax spread out between fewer than fNCellsMax cells.
*
*
General properties:
*
* Component ID: \b PhosMipTrigger
* Library: \b libAliHLTTrigger.so
* Input Data Types: kAliHLTDataTypeESDObject, kAliHLTDataTypeESDTree
* Output Data Types: ::kAliHLTAnyDataType
*
* Mandatory arguments:
*
*
* Optional arguments:
*
*
* Configuration:
*
* \li -emin e
* minimum required energy of the cluster
*
* \li -emax e
* maximum energy of the cluster
*
* \li -ncells e
* Maximum number of cells in cluster
*
*
* By default, configuration is loaded from OCDB, can be overridden by
* component arguments.
*
* Default CDB entries:
* HLT/ConfigHLT/PhosMipTrigger: TObjString storing the arguments
*
* Performance:
*
*
* Memory consumption:
*
*
* Output size:
*
*
* \ingroup alihlt_trigger_components
