Sorry, forgot to mention x-axis units are MeV (while y, are Hz/MeV,
i.e. the differential count rate wrt energy. MC data has been
converted in this unit by considering the muon fluence)<br>

Dear all,<br>
just want to share with you the newest result from Catania Data vs
MC comparison: the comparison has been made by selecting events
with signals from 4 crystals in a column in the matrix above
threshold (to select vertical cosmic rays): note that in data
(blue) and mc (Red) histograms the scale is absolute (Hz/MeV),
i.e. no "ad-hoc" normalization has been used.<br>
Main issues that have been fixed in MC are:<br>
<br>
1) Distribution of primary cosmic rays and their normalization -
according to the proper definition of "flux" as "fluence
differential wrt time"<br>
2) Spread induced in the charge collection due to the finite
crystals attenuation length.<br>
<br>
I'll talk more about these results next Tuesday meeting, but I'd
like to share this good result with you.<br>
<br>
Bests<br>
