Detailed Description

Retrieves information: pmt gain.

Configuration parameters

• DatabaseRetrievalAlg (parameter set, mandatory): configuration for the database; see lariov::DatabaseRetrievalAlg
• UseDB (boolean, default: false): retrieve information from the database
• UseFile (boolean, default: false): retrieve information from a file; not implemented yet
• DefaultGain (real, default: ): Gain returned when /UseDB/ and /UseFile/ parameters are false
• DefaultGainErr (real, default: ): Gain uncertainty returned when /UseDB/ and /UseFile/ parameters are false
