Page 3, between lines 99 and 100: How exactly "the dependence of the peak shapes" on muon kinematics was studied, and how big is the associated systematics ?

Lines 229-232: What was the motivation for Crystal Ball and Crystal Ball+Gaussian for the signal, was the dependence on the background parameterization studied at all ? Only a choice of a second order polynomial is mentioned for the background part. We know that the yield estimation can vary a lot in our pi0 studies. Therefore, this should be explained in more detail. As we can see in Table 3, the Fit function is a quite siginificant source of systematic error.

Section 6.1, from the beginning: the method used for separating prompt and non-prompt decays appears to be confusing. As far as I know, Chris had some questions about it, so I let him comment.
