    "abstract": "The expectation values of a hermitean operator A in (2s+1)(2s+1) specific\ncoherent states of a spin are known to determine the operator unambiguously. As\nshown here, (almost) any other (2s+1)(2s+1) coherent states also provide a\nbasis for self-adjoint operators. This is proven by considering the determinant\nof the Gram matrix associated with the coherent state projectors as a\nHamiltonian of a fictitious classical spin system.",
