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

//   \author: Timo Alho (Jyvaskyla), original version. 
//   [Consultant: D. Silvermyr (ORNL)]
//   Partly based on AliTPCCalibPedestal.
