When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.86566, author = "{LHCf Collaboration}", title = "{Measurement of forward photon production cross-section in proton–proton collisions at $\sqrt{s}$ = 13 TeV with the LHCf detector}", howpublished = "{HEPData (collection)}", year = 2019, note = "\url{https://doi.org/10.17182/hepdata.86566}" }

or, if you prefer, a specific version of the record:

@misc{hepdata.86566.v1, author = "{LHCf Collaboration}", title = "{Measurement of forward photon production cross-section in proton–proton collisions at $\sqrt{s}$ = 13 TeV with the LHCf detector (Version 1)}", howpublished = "{HEPData (collection)}", year = 2019, note = "\url{https://doi.org/10.17182/hepdata.86566.v1}" }

You can also cite this table directly.

@misc{hepdata.86566.v1/t1, author = "{LHCf Collaboration}", title = "{``Table 1'' of ``Measurement of forward photon production cross-section in proton–proton collisions at $\sqrt{s}$ = 13 TeV with the LHCf detector'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2019, note = "\url{https://doi.org/10.17182/hepdata.86566.v1/t1}" }
