    "abstract": "Unsharp spin 1 observables arise from the fact that a residual uncertainty\nabout the actual orientation of the measurement device remains. If the\nuncertainty is below a certain level, and if the distribution of measurement\nerrors is covariant under rotations, a Kochen-Specker theorem for the unsharp\nspin observables follows: There are finite sets of directions such that not all\nthe unsharp spin observables in these directions can consistently be assigned\napproximate truth-values in a non-contextual way.",
