A searchable scientific dataset cataloguing 122 Type Iax supernovae with distances, spectra, and photometry.

Landing page captured for the 2026-09-08 issue.

Field notes

The catalog exposes object-level observational coverage rather than only names and classifications. For example, SN 2005hk is listed with 43 spectra and 568 photometric points across 21 bands, while SN 2012Z has 44 spectra and 583 photometric points. Some distance entries are explicitly calculated from recession velocity using H₀ = 73 km/s/Mpc, making the table useful as a compact research reference.
