Comment to from TWE to birefringence (Click here to view original report: 2816)
For easier comparison with direct measurement with PCI (see elog 2755), I show here the absolute value of delta n flipped both horizontally and vertically .
It seems that the larger delta n area have somehow a close triangular shape.
