When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.77272, author = "{ATLAS Collaboration}", title = "{Search for heavy resonances decaying to a $W$ or $Z$ boson and a Higgs boson in the $q\bar{q}^{(\prime)}b\bar{b}$ final state in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector}", howpublished = "{HEPData (collection)}", year = 2017, note = "\url{https://doi.org/10.17182/hepdata.77272}" }

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

@misc{hepdata.77272.v1, author = "{ATLAS Collaboration}", title = "{Search for heavy resonances decaying to a $W$ or $Z$ boson and a Higgs boson in the $q\bar{q}^{(\prime)}b\bar{b}$ final state in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector (Version 1)}", howpublished = "{HEPData (collection)}", year = 2017, note = "\url{https://doi.org/10.17182/hepdata.77272.v1}" }

You can also cite this table directly.
