Just to clarify Michel's earlier remark, the field norm for the cyclotomics defines the norm in which these vectors are equiangular, and then they will generally **not** be equiangular in the standard norm based on the Hilbert-Schmidt inner product. In the example that he quotes,
$$\|(7\pm 3 \sqrt{5})/32\|_{\mathbb{Q}(\sqrt{5})} = \left[\frac{(7\pm 3 \sqrt{5})}{32} \frac{(7\mp 3 \sqrt{5})}{32}\right]^{1/\deg(\mathbb{Q}[\sqrt{5})]} = \frac{1}{16}.$$
It might be helpful in v2 of the paper if these vectors are called "generalized equiangular" or "equiangular with respect to the field norm", as this will help avoid confusion.
