26 // Class AliEMCALCalibHistoProducer accumulating histograms
27 // with amplitudes per EMCAL channel
28 // It is intended to run at DAQ computers (LDC, GDC, HLT or MOOD)
29 // and it fills the histograms with amplitudes per channel.
30 // Usage example see in EMCAL/macros/Shuttle/AliEMCALCalibHistoProducer.C
