Previous theoretical work, to first order, demonstrated that branch points are markers for photons carrying orbital angular momentum (OAM), but gave to indication of the flux associated with a given branch point distribution. In a parallel effort, the OAM flux as a ratio of the total flux is calculated, but that work relies on knowing the non-zero elements in the slope discrepancy Hilbert space. Here, we calculate the “size” of the slope discrepancy Hilbert space for our previously published data.
