When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.61707, author = "{ATLAS Collaboration}", title = "{A measurement of the ratio of the W and Z cross sections with exactly one associated jet in pp collisions at sqrt(s) = 7 TeV with ATLAS}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61707}" }

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

@misc{hepdata.61707.v1, author = "{ATLAS Collaboration}", title = "{A measurement of the ratio of the W and Z cross sections with exactly one associated jet in pp collisions at sqrt(s) = 7 TeV with ATLAS (Version 1)}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61707.v1}" }

You can also cite this table directly.

@misc{hepdata.61707.v1/t2, author = "{ATLAS Collaboration}", title = "{``Table 2'' of ``A measurement of the ratio of the W and Z cross sections with exactly one associated jet in pp collisions at sqrt(s) = 7 TeV with ATLAS'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61707.v1/t2}" }
