When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.90847, author = "{CMS Collaboration}", title = "{Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} =$ 8 TeV}", howpublished = "{HEPData (collection)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.90847}" }

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

@misc{hepdata.90847.v1, author = "{CMS Collaboration}", title = "{Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} =$ 8 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.90847.v1}" }

You can also cite this table directly.

@misc{hepdata.90847.v1/t4, author = "{CMS Collaboration}", title = "{``Figure 4'' of ``Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} =$ 8 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.90847.v1/t4}" }
