19 | // Class AliPHOSCalibHistoProducer accumulating histograms | |
20 | // with amplitudes per PHOS channel | |
21 | // It is intended to run at DAQ computers (LDC, GDC, HLT or MOOD) | |
22 | // and it fills the histograms with amplitudes per channel. | |
23 | // Usage example see in PHOS/macros/Shuttle/AliPHOSCalibHistoProducer.C | |
