Hi Antonio,

	this looks quite fine. I have a few comments.

 - the base line fit uses mes above 5.22 GeV.
 - can you change the argus line to blue
 - the label for all should be signal+all background
 - can you move the legend it bit up

 - two things to discuss:

	- how many bins should we use
        - should we add the signal PDF also?

And two question:

 - is this plot done for the new selection?
 - why does the fit on all semileptonic events for 100 bins so bad?

Cheers,

	Wolfgang
