How can I calculate the "pull" ?

[rajeevneutrino]

Dear authors,

I am finding the chisq_min for the relevant WCs (say C9_bsmumu and C10_bsmumu) using the b2smumu data. I wanted to estimate the goodness of the fit with the help of "pull". As usual, I define pull=sqrt(chisq_min(SM)/dof - chisq_min(NP)/dof).

In flavio, I use:
from flavio.math.optimize import minimize
def chi2(x):
return -2*FL(x)
chi2_min = minimize(chi2,[0,0])
chi2_min

I get the best fit points of the WCs by doing the above steps. But how can I get the information about chisq_min(SM)/dof and chisq_min(NP)/dof ?

Kindly help me.

Thanks and Regards,
Rajeev
