## Statement

The ledger’s degree presentation of the global-fit CKM Dirac phase is δ = 66.12° ± 1.43°.

## Primary source

Paper 3, §2.1, Comparator refresh: two presentations of the global-fit phase, PDF p.50: "the global-fit Dirac phase δ = 1.154 ± 0.025 rad gives +1.40σ in that published representation, which is primary (R-29; the degree cells 66.12◦ ± 1.43◦ give +1.41σ)"
