I noticed a feature in the ITMX GigE camera image when I pulled it up yesterday.  It appears to have a very dark line going through the bright features on the left side of the image.  After taking a snapshot and adjusting the image, I see a to be a dark line at the top and on the right side as well.  I calculated the beam shift using the image, which is fraught with error, but still a decent ballpark measurement, which came up with a beam shift in -X of 12mm.  Will be interesting to see what the high-res images show.
