\subsection{Detailed Description}
The tracker chi2 vs deflection cut. 

Events whose track has been fitted with a chi2 greater than Chi2(eta) are discarded. Chi2(eta) is a function which gives the maximum value of chi2 associated to a certain deflection eta; in current implementation it is parameterized as:

Chi2(eta) = p0 + p1 $\ast$ eta$^\wedge$2 + p2 $\ast$ eta $^\wedge$4

where p0, p1 and p2 are parameters.
