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
31//
