When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.54850, author = "{ATLAS Collaboration}", title = "{Charged-particle multiplicities in pp interactions at sqrt(s) = 900 GeV measured with the ATLAS detector at the LHC}", howpublished = "{HEPData (collection)}", year = 2010, note = "\url{https://doi.org/10.17182/hepdata.54850}" }

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

@misc{hepdata.54850.v1, author = "{ATLAS Collaboration}", title = "{Charged-particle multiplicities in pp interactions at sqrt(s) = 900 GeV measured with the ATLAS detector at the LHC (Version 1)}", howpublished = "{HEPData (collection)}", year = 2010, note = "\url{https://doi.org/10.17182/hepdata.54850.v1}" }

You can also cite this table directly.

@misc{hepdata.54850.v1/t4, author = "{ATLAS Collaboration}", title = "{``Table 4'' of ``Charged-particle multiplicities in pp interactions at sqrt(s) = 900 GeV measured with the ATLAS detector at the LHC'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2010, note = "\url{https://doi.org/10.17182/hepdata.54850.v1/t4}" }
