Supplemental figures: Direct photon production at low transverse momentum in proton-proton collisions at $\mathbf{\sqrt{s}=2.76}$ and 8 TeV

This note provides supplemental figures for the paper ``Direct photon production at low transverse momentum in proton-proton collisions at $\sqrt{s}=2.76$ and 8 TeV'' \cite{Acharya:2018cpp}. The decay-photon simulation figures for $\sqrt{s}=8$ TeV are provided as well as individual and combined correction factors of the inclusive photons for both reconstruction methods. In addition, plots of the inclusive photon spectra for both systems as well as standalone figures of the direct photon excess ratios or their corresponding theory calculations are provided. Furthermore, a comparison of $R_\gamma$ between pp and Pb--Pb collisions in three centrality classes is made.
