Just a reminder that one should not expect the carbon hole to be centered.
According to Dave Meekins (as of last week), the holey carbon target was not fully surveyed into position. It _should_ be accurately centered at to the ~0.5--0.8mm level, but one should not be adjusting the beam position to center up the hole in the raster pattern and then assume that the beam will also be centered on the production target(s).
