When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.79847, author = "{ATLAS Collaboration}", title = "{Measurement of the $W^+W^-$ production cross section in $pp$ collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV with the ATLAS experiment}", howpublished = "{HEPData (collection)}", year = 2017, note = "\url{https://doi.org/10.17182/hepdata.79847}" }

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

@misc{hepdata.79847.v1, author = "{ATLAS Collaboration}", title = "{Measurement of the $W^+W^-$ production cross section in $pp$ collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV with the ATLAS experiment (Version 1)}", howpublished = "{HEPData (collection)}", year = 2017, note = "\url{https://doi.org/10.17182/hepdata.79847.v1}" }

You can also cite this table directly.

@misc{hepdata.79847.v1/t3, author = "{ATLAS Collaboration}", title = "{``Table 3'' of ``Measurement of the $W^+W^-$ production cross section in $pp$ collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV with the ATLAS experiment'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2017, note = "\url{https://doi.org/10.17182/hepdata.79847.v1/t3}" }
