[BDXlist] Catania measurements: Data vs MC comparison

[Marco Battaglieri]

Dear Andrea,
the comparison of the 16 channels of the calorimeter looks wonderful!!
Whit this result in hands we can really think to write a paper about the 
prototype  including the comparison withthe  MC.
What about the 'old' crystal? do you have any results?
Cheers
Marco
