Dear Claude et al.,

I have just implemented an improved version of the impurity capture plot
which (a) groups together 15 consecutive runs, and (b) shows error
bars on each point.  The error bars are statistical only; the "control"
points (green) give an idea of the systematic background.  The new plot
appears on the online analysis page just below the original version.
It currently indicates a yield of about 14 +/- 2 ppm.

Thanks,
