= Momentum-bin Kurie ordinate
{title2=$K(p)=\sqrt{N(p)/[p^2F(p)]}$}
For counts $N(p)dp$ per <electron> <momentum> interval, the allowed spectrum is proportional to $p^2F(p)(Q-T)^2dp$ when recoil and <neutrino> <mass> are neglected. Thus the displayed ordinate is linear in <kinetic energy> under a constant-shape assumption. Counts per kinetic-energy interval instead have the factor $pE_e$ in <natural units>; the Jacobian $dT/dp=p/E_e$ accounts for the difference. Mixing those two binning conventions changes the inferred ordinate.
