When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.27025, author = "{CMD-2 Collaboration}", title = "{Study of the Process e+ e- ---> eta gamma in c.m. Energy Range 600-1380 MeV at CMD-2}", howpublished = "{HEPData (collection)}", year = 1970, note = "\url{https://doi.org/10.17182/hepdata.27025}" }

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

@misc{hepdata.27025.v1, author = "{CMD-2 Collaboration}", title = "{Study of the Process e+ e- ---> eta gamma in c.m. Energy Range 600-1380 MeV at CMD-2 (Version 1)}", howpublished = "{HEPData (collection)}", year = 1970, note = "\url{https://doi.org/10.17182/hepdata.27025.v1}" }

You can also cite this table directly.

@misc{hepdata.27025.v1/t1, author = "{CMD-2 Collaboration}", title = "{``Table 1'' of ``Study of the Process e+ e- ---> eta gamma in c.m. Energy Range 600-1380 MeV at CMD-2'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 1970, note = "\url{https://doi.org/10.17182/hepdata.27025.v1/t1}" }
