11 | // \brief Description: | |
12 | // A help class for monitoring and calibration tools: MOOD, AMORE etc., | |
13 | // that can process events from a standard AliCaloRawStream, | |
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. | |
