When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.139098, author = "{PHENIX Collaboration}", title = "{Transverse single-spin asymmetry of midrapidity $\pi^{0}$ and $\eta$ mesons in $p$+Au and $p$+Al collisions at $\sqrt{s_{_{NN}}}=$ 200 GeV}", howpublished = "{HEPData (collection)}", year = 2023, note = "\url{https://doi.org/10.17182/hepdata.139098}" }

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

@misc{hepdata.139098.v1, author = "{PHENIX Collaboration}", title = "{Transverse single-spin asymmetry of midrapidity $\pi^{0}$ and $\eta$ mesons in $p$+Au and $p$+Al collisions at $\sqrt{s_{_{NN}}}=$ 200 GeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2023, note = "\url{https://doi.org/10.17182/hepdata.139098.v1}" }

You can also cite this table directly.

@misc{hepdata.139098.v1/t2, author = "{PHENIX Collaboration}", title = "{``Figure 2 (b)'' of ``Transverse single-spin asymmetry of midrapidity $\pi^{0}$ and $\eta$ mesons in $p$+Au and $p$+Al collisions at $\sqrt{s_{_{NN}}}=$ 200 GeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2023, note = "\url{https://doi.org/10.17182/hepdata.139098.v1/t2}" }
