Ratio of inclusive photon invariant cross sections obtained with the PCM and \EMC\ methods to the TCM fit, \Eq{eq:Bylinkin} of the combined inclusive photon spectrum in pp collisions at $\sqrt{s}=2.76$ TeV~(\textit{left}) and 8 TeV~(\textit{right}) Statistical uncertainties are given by vertical lines and systematic uncertainties are visualized by the height of the boxes, while the bin widths are represented by the widths of the boxes. | |
