Left: Comparison of the $E/p$ distribution between real (black) and simulated (red) data for electron candidates with $3.0 \pT 4$ \GeVc\ in pp collisions at \sthirteen Gaussian fits with exponential tails to both sides are superimposed for both distributions in the corresponding color. The truncated means for data and \gls{MC} are indicated by vertical colored lines The truncation and signal integration window is indicated by vertical dashed gray lines Right: Data and simulation comparison of width (top) and mean (bottom) of the $E/p$ distributions of electrons as a function of transverse momentum in \pp\ collisions at \sthirteen. Fit functions are shown as dashed lines, where their functional form is given in the respective legends.
