 Direct photon excess ratios obtained with the PCM, \EMC\ and \PCMEMC\ methods 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.
