When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.89051, author = "{CMS Collaboration}", title = "{Measurement of the top quark mass in the all-jets final state at $\sqrt{s}=$ 13 TeV and combination with the lepton+jets channel}", howpublished = "{HEPData (collection)}", year = 2019, note = "\url{https://doi.org/10.17182/hepdata.89051}" }

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

@misc{hepdata.89051.v1, author = "{CMS Collaboration}", title = "{Measurement of the top quark mass in the all-jets final state at $\sqrt{s}=$ 13 TeV and combination with the lepton+jets channel (Version 1)}", howpublished = "{HEPData (collection)}", year = 2019, note = "\url{https://doi.org/10.17182/hepdata.89051.v1}" }

You can also cite this table directly.

@misc{hepdata.89051.v1/t1, author = "{CMS Collaboration}", title = "{``Table 1'' of ``Measurement of the top quark mass in the all-jets final state at $\sqrt{s}=$ 13 TeV and combination with the lepton+jets channel'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2019, note = "\url{https://doi.org/10.17182/hepdata.89051.v1/t1}" }
