    keyword=Tune B Left Arm Sieve very clear with proper VDC position offsets

    There are a few offsets which represent small differences between the VDC true position and orientation and an ideal positioning. These were basically assumed to be 0 until now. As per Nilanga I took some values from the PVDIS databases and the left arm came out significantly better for tune B.

    I can now see many more holes very clearly (Fig 1). There is a missing hole in the corner, which is asymmetric from the top and bottom (maybe a hint of it is there). Additionally, I can only see one of the two "missing holes", C and E in Fig 2. B and D are still invisible.

    The right arm doesn't seem to have improved that much, Fig 3, but it very well could just be matrix elements. I'll continue with trying to improve things.
