Detailed Description

Retrieves channel information: pedestal and RMS.

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
DefaultCollMean (real, default: 400.0): pedestal value returned for collection plane channels when /UseDB/ and /UseFile/ parameters are false
DefaultIndMean (real, default: 2048.0): pedestal value returned for induction plane channels when /UseDB/ and /UseFile/ parameters are false
DefaultCollRms (real, default: 0.3): pedestal RMS value returned for collection plane channels when /UseDB/ and /UseFile/ parameters are false
DefaultIndRms (real, default: 0.3): pedestal RMS value returned for induction plane channels when /UseDB/ and /UseFile/ parameters are false
DefaultMeanErr (real, default: 0.0): error on the pedestal value for all channels returned when /UseDB/ and /UseFile/ parameters are false
DefaultRmsErr (real, default: 0.0): error on the RMS value for all channels returned when /UseDB/ and /UseFile/ parameters are false
