10 // \brief Description:
11 // A help class for monitoring and calibration tools: MOOD, AMORE etc.,
12 // that can process events from a standard AliCaloRawStream,
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).
18 // \author: Josh Hamblen (UTenn), original version.
19 // [Consultant: D. Silvermyr (ORNL)]
20 // Partly based on AliCaloCalibPedestal.
