ALICE data compared to previous measurements of isolated-photon spectra in ${\rm pp}$ and ${\rm p}\overline{\rm p}$ collisions as a function of $x_{\rm T }$ where the invariant cross sections have been scaled by $(\sqrt{s})^n$ with $n=4.5$ (taken from Ref. [2]). For this comparison, only the results covering midrapidity are shown.
