Resulting residuals - origin could be:

• due to the MS - visible in the qPt dependence resp. sqrt(dEdx)*qpt
• due rotation approximation - should be seen as function of fP[2]

[Trenchcoat95]

sigma as function of qpt:

[Trenchcoat95]

sqigma qpt as function of sinphi:

[miranov25]

Remaining discrepancy can be due to the difference in smearing - in covariance smearing relative in E and in MC in relative in p

[miranov25]

Smearing will be still tuned later -working on the brag peak position fluctuation later ...
