Used the piece chuck like always, but 4 out of 5 of samples were misaligned by 5um at most. It seems that the top left corner is misaligned worse than the other corners, which implies that the sample was rotated CC. (usually 1 out o 5 samples would shift in x or y direction, but never did they rotate like this time)
