    • The “flux” is evaluated with the standard expression, (Formula presented) Neither this “flux” nor the “probability density” (Formula presented) obtained from Eq. (32) have the proper dimensions. This is due to the “continuum” normalization used for the eigenstates of (Formula presented) which are not square integrable. The appropriate dimensions are of course obtained by integrating these objects over time to form wave packets

    • According to the terminology of Ref
    • According to the terminology of Ref. 11, any self-adjoint operator is “sharp.” However, referring to the eigenstates of the self-adjoint time operators, we use the sharp/unsharp concept in a way closer to the conventional usage of the words. Being sharp is “having an edge or point” or “being abrupt.”

    • A similar construction was carried out by Paul with a flat weighting function instead of a Gaussian. However, while he dismissed these states because they do not belong to (Formula presented) this is not essential to construct a POVM
