Now we discuss the way to compute the electronic stopping for the off-channeling trajectory case. The procedure have been displayed in Figure  \ref{fig:fit_off_channel}. The sharp peak at distance ($\sim 16~a_0$) shows that the proton is in the vicinity of a host atom whiles the lesser peaks indicates that the proton is not very close to a host atom. To obtain the electronic stopping we compute the slopes of the curves by a linear fit of the form $y = a + bx$ (black lines) to the data starting at $x = 5~a_0$ (to eliminate the transient region) to a given maximum position $x$. The slope ($b$) gives the electronic stopping for the off-channeling case.% %We have displayed the procedure used in obtaining the electronic stopping for the off-channeling trajectory case in Figure \ref{fig:fit_off_channel}.
