TAMA T1 absorption measurement
This sample absorption has been remeasured as there was some discrepancy with measurement few years old.
This one agrees with the one I did few months ago : absorption is around 18 ppm
(Pin = 7.316W, Pt = 6.29W, R = 0.8342 ppm/cm)
There are however strange patterns on the XZ YZ measurements that were not present before.
