Supplemental figures: $\pi^{0}$ and $\eta$ meson production in proton-proton collisions at $\sqrt{s}=8$ TeV

This note provides supplemental figures for the paper ``$\pi^{0}$ and $\eta$ meson production in proton-proton collisions at $\sqrt{s}=8$ TeV''. The set of example plots for both neutral mesons showing the invariant mass distributions for each reconstruction method for all calorimeter triggers used in analysis is completed. Further plots, showing the neutral meson spectra as well as additional plots concerning the $\eta/\pi^{0}$ ratio, are provided. More details about the determination of integrated yields and mean transverse momenta are also contained in this note.
