χ² profiles, two-dimensional allowed regions and the machine-readable tables for this release are available from the authors on request.
Bari group results — second release
Δχ² tables, one- and two-dimensional profiles and the figures of the Bari
global analysis including the JUNO second release, served as an interactive
notebook that runs entirely in the browser. The underlying
.npz and text tables are downloadable from the same page.
Access is restricted while the release is internal. Credentials on request.
