11 // \brief Description:
12 // A help class for monitoring and calibration tools: MOOD, AMORE etc.,
13 // that can process events from a standard AliCaloRawStreamV3,
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.
19 // \author: Timo Alho (Jyvaskyla), original version.
20 // [Consultant: D. Silvermyr (ORNL)]
21 // Partly based on AliTPCCalibPedestal.
