When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.69306, author = "{ATLAS Collaboration}", title = "{Measurement of transverse energy-energy correlations in multi-jet events in $pp$ collisions at $\sqrt{s} = 7$ TeV using the ATLAS detector and determination of the strong coupling constant $\alpha_{\mathrm{s}}(m_Z)$}", howpublished = "{HEPData (collection)}", year = 2015, note = "\url{https://doi.org/10.17182/hepdata.69306}" }

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

@misc{hepdata.69306.v1, author = "{ATLAS Collaboration}", title = "{Measurement of transverse energy-energy correlations in multi-jet events in $pp$ collisions at $\sqrt{s} = 7$ TeV using the ATLAS detector and determination of the strong coupling constant $\alpha_{\mathrm{s}}(m_Z)$ (Version 1)}", howpublished = "{HEPData (collection)}", year = 2015, note = "\url{https://doi.org/10.17182/hepdata.69306.v1}" }

You can also cite this table directly.

@misc{hepdata.69306.v1/t1, author = "{ATLAS Collaboration}", title = "{``Table 1'' of ``Measurement of transverse energy-energy correlations in multi-jet events in $pp$ collisions at $\sqrt{s} = 7$ TeV using the ATLAS detector and determination of the strong coupling constant $\alpha_{\mathrm{s}}(m_Z)$'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2015, note = "\url{https://doi.org/10.17182/hepdata.69306.v1/t1}" }
