Mike,
We may be trying to read too much from the plots. The intent of the plots was primarily to gauge the fraction of surface area that allows for full tile thickness as well as to show we have not encroached on the FW at any locations beyond our minimum acceptable amount.
The orignal plots compares distance at each measurement point on the VV to the FW for the design and the as-built. However, each dataset is sorted independently to allow an assessment of the area fraction, but not to do a point to point comparison to see if each point is in or out of tolerance. If I don't sort independently but allow a point to point comparison, I produce a plot like the one attached which conveys the fact that many points are out of tolerance (we knew that already), but do not get a sense of how it impacts the extent of full tile coverage.
I'm sorry for the confusion, but I haven't come up with a better way of looking at the data. I welcome any suggesting you may have.

Art,
Your plot doesn't seem to represent the data by shear numbers comparison.
There are 794 points that are out of tolerance to the inside and 856 that are out of tolerance to the outside. Scaling the distance on the horizontal axis, it doesn't seem to equal all the points out of tolerance to the inside. I realize that this is a very crude method.
Also I don't understand why the out of tolerance points are all at 3+" distance from the first wall. Nothing seems to be out of tolerance close to the first wall. Is that correct? I though that the region repaired was where the plasma is closest to the vessel wall. So we should see hundreds of points out of tolerance where the repair was made at the shorter distance regions (left side) of your plot.
Finally, what is the second plot representing?
Thanks,

Mike,
Attached is plot of all the scan points for VVSA3 relative to our design targets. From a FW encroachment standpoint, at this point VVSA3 looks comparable or slightly better than VVSA1. At the closest point (and its really only 1 or 2 points of the 8000+) we have moved in but are within tolerance. The area of the VV where we can support a full thickness tile (the horizontal region of the plot) has shrunk ~ 5%, comparable to what we saw on VVSA1.
Hopefully this data is taken in the relaxed state (no spider) and is reproduceable.

The VVSA #3 scan is complete.
Files are published to the public ftp site in the VVSA #3 folder.

Subject: Error uploading point cloud inspection data.
Mike, I can't seem to upload the latest VVSA 3 profile inspection data. Am I using the correct directory? I've tried both of the following with no luck:
ftp://ftp.pppl.gov/priv/vv-sa-mv/
ftp://ftp.pppl.gov/pub/vio-vvsa/
