Query: Precise Determination of Charge Dependent Pion-Nucleon-Nucleon Coupling
  Constants   We undertake a covariance error analysis of the pion-nucleon-nucleon coupling
constants from the Granada-2013 np and pp database comprising a total of 6720
scattering data below LAB energy of 350 MeV. Assuming a unique pion-nucleon
coupling constant in the One Pion Exchange potential above a boundary radius
$r_c=3 {\rm fm}$ we obtain $f^2=0.0763(1)$. The effects of charge symmetry
breaking on the $^3P_0$, $^3P_1$ and $^3P_2$ partial waves are analyzed and we
find $f_{p}^2 = 0.0761(4)$, $f_{0}^2 = 0.0790(9)$ and $f_{c}^2 = 0.0772(6)$
with a strong anti-correlation between $f_c^2$ and $f_0^2$. We successfully
test normality for the residuals of the fit. Potential tails in terms of
different boundary radii as well as chiral Two-Pion-Exchange contributions as
sources of systematic uncertainty are also investigated.
