When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.156226, author = "{Belle Collaboration}", title = "{High-Statistics Study of the $\tau^- \to \pi^- \pi^0 \nu_\tau$ Decay}", howpublished = "{HEPData (collection)}", year = 2025, note = "\url{https://doi.org/10.17182/hepdata.156226}" }

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

@misc{hepdata.156226.v1, author = "{Belle Collaboration}", title = "{High-Statistics Study of the $\tau^- \to \pi^- \pi^0 \nu_\tau$ Decay (Version 1)}", howpublished = "{HEPData (collection)}", year = 2025, note = "\url{https://doi.org/10.17182/hepdata.156226.v1}" }

You can also cite the 3 data tables individually.
