When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.14320, author = "{OPAL Collaboration}", title = "{The Forward - backward asymmetry of e+ e- ---> b anti-b and e+ e- ---> c anti-c using leptons in hadronic Z0 decays}", howpublished = "{HEPData (collection)}", year = 1993, note = "\url{https://doi.org/10.17182/hepdata.14320}" }

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

@misc{hepdata.14320.v1, author = "{OPAL Collaboration}", title = "{The Forward - backward asymmetry of e+ e- ---> b anti-b and e+ e- ---> c anti-c using leptons in hadronic Z0 decays (Version 1)}", howpublished = "{HEPData (collection)}", year = 1993, note = "\url{https://doi.org/10.17182/hepdata.14320.v1}" }

You can also cite this table directly.

@misc{hepdata.14320.v1/t4, author = "{OPAL Collaboration}", title = "{``Table 4'' of ``The Forward - backward asymmetry of e+ e- ---> b anti-b and e+ e- ---> c anti-c using leptons in hadronic Z0 decays'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 1993, note = "\url{https://doi.org/10.17182/hepdata.14320.v1/t4}" }
