$E/p$ distribution for electron candidates selected by applying $-1 \leq n\sigma^{\textrm{TPC}}_{e^\pm} \leq 3$ (black open circles), and for hadrons with $-10 \leq n\sigma^{\textrm{TPC}}_{e^\pm} \leq -4$ (blue dots) scaled to match the electron distribution in the range indicated by the blue shaded box. The red diamonds reflect the remaining signal distribution after background subtraction and the corresponding signal fit using a Gaussian with an exponential tail is overlaid in dark red. The distributions are shown for various event triggers in \pp\ collisions at \sthirteen\ in different \pT\ intervals.
