The parameters $\\theta_{12}$, $\\theta_{13}$, $\\Delta m^2_{21}$, and $|\\Delta m^2_{3\\ell}|$ ($\\ell = 1,2$) are well-determined with relative precision at $3\\sigma$ of about 13\\%, 8\\%, 15\\%, and 6\\%, respectively. The third mixing angle $\\theta_{23}$ still suffers from the octant ambiguity, with no clear indication of whether it is larger or smaller than $45^\\circ$. The determination of the leptonic CP phase $\\delta_{CP}$ depends on the neutrino mass ordering: for normal ordering the global fit is consistent"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The global fit including long-baseline, reactor and IceCube atmospheric data results into an almost equally good fit for both orderings.
