When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.55126, author = "{CMS Collaboration}", title = "{Measurement of the Underlying Event Activity in Proton-Proton Collisions at 0.9 TeV}", howpublished = "{HEPData (collection)}", year = 2010, note = "\url{https://doi.org/10.17182/hepdata.55126}" }

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

@misc{hepdata.55126.v1, author = "{CMS Collaboration}", title = "{Measurement of the Underlying Event Activity in Proton-Proton Collisions at 0.9 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2010, note = "\url{https://doi.org/10.17182/hepdata.55126.v1}" }

You can also cite this table directly.

@misc{hepdata.55126.v1/t6, author = "{CMS Collaboration}", title = "{``Table 6'' of ``Measurement of the Underlying Event Activity in Proton-Proton Collisions at 0.9 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2010, note = "\url{https://doi.org/10.17182/hepdata.55126.v1/t6}" }
