10// \brief Description:
11// A help class for monitoring and calibration tools: MOOD, AMORE etc.,
32cd4c24 12// that can process events from a standard AliCaloRawStreamV3,
bd83f412 13// most usually from LED/pulser runs. It stores signal info as
14// typical (highest) amplitude vs time in TGraphs (one per channel)
15// or TProfiles if we decide to just store the averages (and not all points)
16// for the detectors (EMCAL and PHOS).
