| Popis: | We show that, when an approximation used in this prior work is removed, the resulting improved calculation yields an alternative derivation, in the particular case studied, of the accidental curvature constraint of Hellmann and Kaminski. The result is at the same time extended to apply to almost all non-degenerate Regge-like boundary data and a broad class of face amplitudes. This resolves a tension in the literature. 8 pages; Addendum to arXiv:1704.04817. Title changed in accordance with editor decision, end of introduction updated and clarified, proof of non-negativity of Im a expanded, references added, and typos corrected |
