11// \brief Description:
12// A help class for monitoring and calibration tools: MOOD, AMORE etc.,
32cd4c24 13// that can process events from a standard AliCaloRawStreamV3,
a235e2bc 14// most usually from LED/pulser runs. It stores signal info as
15// typical (highest) amplitude, and pedestal info in geometrically-binned
16// 2D profiles of the detectors (EMCAL and PHOS).
17// Comparisons (ratios and differences) can be done with references.
