This is especially important for the electron measurements due to the proton contamination. This contamination will be corrected for by using the measured proton spectrum and the simulated response (i.e. the likely-hood of a proton to end up in the electron channel) in order to estimate the number of protons in the electron channels and subtract this from the measured electron channel count rate. A detailed mathematical description of the systematic uncertainties introduced by this method is given in section \ref{sec:error_estimation_eq}.\newline +The derived uncertainties for the protons and electrons in their corresponding high-accuracy and high-statistics data products are summarized below. Note that while the proton uncertainty is derived from the expected counting statistics, the electron uncertainties also include the systematic uncertainties caused by proton contamination. \subsubsection*{High-accuracy proton channels} It has been shown that requiring a coincidence from SDA up to SDE for protons allows for utilizing the Cherenkov in order to separate at 2~GeV. Using this coincidence, protons from 150~MeV up to 2~GeV can be detected in \begin{itemize} - \item five channels on 10ks time resolution with 2.7\% uncertainty - \item two channels on 3ks time resolution with 3.1\% uncertainty + \item five channels on 10ks time resolution with 2.7\% stat. uncertainty + \item two channels on 3ks time resolution with 3.1\% stat. uncertainty \end{itemize} This would also provide an integral channel for protons above 2~GeV. Note that the protons up to 150~MeV can also improve the statistics utilizing the stopping channels. \newline
