Description

The Beam Tilt focusing has been working poorly for me. It is generally ~1 micron off.(on T2, with 200kV alignments. Both with the 2nd and 3rd C2 aperture.)
I have checked that my alignment is good, this is not the problem.
Stage Tilt focusing is working well.

Went through defocus calibration in Beam Tilt node with Erica after checking eucentric focus and rotation center. It is fine now.
