Attached - no selection at all in this case (that means that
basically ALL what we see in the data are cosmics, since just
cosmics where in the simulation)<br>
Quality is good - but the calibration is not trivial in this case -
hence I do not know how to improve this.<br>

<div class="moz-cite-prefix">Dear Andrea,<br>
the comparison of the 16 channels of the calorimeter looks
wonderful!! <br>
Whit this result in hands we can really think to write a paper
about the prototype including the comparison withthe MC.<br>
What about the 'old' crystal? do you have any results?<br>
Cheers<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>
Andrea<br>
