The fit formula with tau

$\begin{cases} r_{AWI}=P[1] (\eta- \eta_{cr}) +P[2] \mu\\ \end{cases}$ In the above fit we are treating $$\eta_{cr}$$ and $$m_{cr}$$ as fits parameters, so $\eta_{cr}=P[0]$

$\begin{gather} \chi^2/d.o.f.=0.246525 \\ P[0]=-1.21126\pm (0.0074) \\ P[1]=-0.962676\pm (0.019) \\ P[2]=0.285741\pm (0.25) \\ \end{gather}$ {$\begin{gather} C=\begin{pmatrix} 1& -0.0037& -0.00312\\ -0.0037& 1& 0.0042\\ -0.00312& 0.0042& 1\\ \end{pmatrix} \end{gather}$}
