When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.27714, author = "{SACLAY-SERPUKHOV-DUBNA-MOSCOW Collaboration}", title = "{Polarization Measurements in pi+ p, K+ p and p p Elastic Scattering at 45-GeV/c and Comparison with Regge Phenomenology}", howpublished = "{HEPData (collection)}", year = 1977, note = "\url{https://doi.org/10.17182/hepdata.27714}" }

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

@misc{hepdata.27714.v1, author = "{SACLAY-SERPUKHOV-DUBNA-MOSCOW Collaboration}", title = "{Polarization Measurements in pi+ p, K+ p and p p Elastic Scattering at 45-GeV/c and Comparison with Regge Phenomenology (Version 1)}", howpublished = "{HEPData (collection)}", year = 1977, note = "\url{https://doi.org/10.17182/hepdata.27714.v1}" }

You can also cite this table directly.

@misc{hepdata.27714.v1/t1, author = "{SACLAY-SERPUKHOV-DUBNA-MOSCOW Collaboration}", title = "{``Table 1'' of ``Polarization Measurements in pi+ p, K+ p and p p Elastic Scattering at 45-GeV/c and Comparison with Regge Phenomenology'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 1977, note = "\url{https://doi.org/10.17182/hepdata.27714.v1/t1}" }
