When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.72856, author = "{ATLAS Collaboration}", title = "{Measurements of fiducial cross-sections for $t\bar{t}$ production with one or two additional $b$-jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV using the ATLAS detector}", howpublished = "{HEPData (collection)}", year = 2016, note = "\url{https://doi.org/10.17182/hepdata.72856}" }

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

@misc{hepdata.72856.v1, author = "{ATLAS Collaboration}", title = "{Measurements of fiducial cross-sections for $t\bar{t}$ production with one or two additional $b$-jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV using the ATLAS detector (Version 1)}", howpublished = "{HEPData (collection)}", year = 2016, note = "\url{https://doi.org/10.17182/hepdata.72856.v1}" }

You can also cite this table directly.

@misc{hepdata.72856.v1/t8, author = "{ATLAS Collaboration}", title = "{``Table 8'' of ``Measurements of fiducial cross-sections for $t\bar{t}$ production with one or two additional $b$-jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV using the ATLAS detector'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2016, note = "\url{https://doi.org/10.17182/hepdata.72856.v1/t8}" }
