When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.60017, author = "{ATLAS Collaboration}", title = "{Search for diphoton events with large missing transverse momentum in 7 TeV proton-proton collision data with the ATLAS detector}", howpublished = "{HEPData (collection)}", year = 2012, note = "\url{https://doi.org/10.17182/hepdata.60017}" }

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

@misc{hepdata.60017.v1, author = "{ATLAS Collaboration}", title = "{Search for diphoton events with large missing transverse momentum in 7 TeV proton-proton collision data with the ATLAS detector (Version 1)}", howpublished = "{HEPData (collection)}", year = 2012, note = "\url{https://doi.org/10.17182/hepdata.60017.v1}" }

You can also cite this table directly.

@misc{hepdata.60017.v1/t2, author = "{ATLAS Collaboration}", title = "{``Table 2'' of ``Search for diphoton events with large missing transverse momentum in 7 TeV proton-proton collision data with the ATLAS detector'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2012, note = "\url{https://doi.org/10.17182/hepdata.60017.v1/t2}" }
