TRANSCRIPT
Software per l'analisi
� Il codice è basato su ROOT
� ROOT è un Object Oriented Analysis Framework
� Il linguaggio di programmazione è C++
�
Le classi di partenza sono state sviluppate dal gruppo di Mainz
� A Torino si è optato per un ampliamento e completamento della struttura delle classi.
