RunInfo:
All processes that can produce prompt photon pairs, e.g. $jj \to jj$,
$jj \to j\gamma$ and $jj \to \gamma \gamma$.
Non-prompt photons from hadron decays like $\pi$ and $\eta$ have been
corrected for.

Description:
Direct photon pair production cross sections are measured using 4.2 fb$^{-1}$
of data. They are binned in diphoton mass, the transverse momentum of the
diphoton system, the azimuthal angle between the photons, and the polar
scattering angle of the photons. Also available are double differential cross
sections considering the last three kinematic variables in three diphoton
mass bins.
Note, the numbers in version 1 of the arXiv preprint were missing the dM
normalisation in the double differential cross sections. This has been
reported to and fixed by the authors in v2 and the journal submission.
HepData as well as the Rivet analysis have also been updated.
