Figure \ref{fig:log_stopping_power} shows the log scale of Figure \ref{fig:stopping_power}. At projectile velocities, $v < 0.1 ~\mathrm{a.u.}$ there is a deviation from linearity of the S_e for the channeling case. We attribute this observation to the crystalline structure of copper???. The error bars (darkgreen crosses) are smaller than the calculated value (of point size); for example at $v = 0.08 ~\mathrm{a.u.}$ the value of S_e is $0.0101704 $\pm 0.0101704  ~\mathrm{E_h/a_0}$ but our fitting procedure produces the error limit of $2.291 \times 10^{-6} ~\mathrm{E_h/a_0}$ and therefore the error bars are practically invisible in the figure. Throught the studied velocity regime the limit of the error bar lies between $10^{-7}$ to $10^{-4}$. At higher velocities our S_e results underestimates the experimental findings owing to lack of core electron effects which are not included our calculations. The importance of core electrons has been discussed earlier by Scheife {\em et al}\cite{Schleife_2015}.
