12x, Aq at BCM1, and Double Differences through 19 slugs. 

Switched BCM from 3 to 1 for the Aq plot since that is what we are now using.

The large position differences for 12x at slug 19 are from large outliers. 
Excluding differences with magnitudes greater than 100 microns leaves 
differences at 12x = 10 nm. In any case, this slug being large and negative 
helps bring down the grand averaged mean.
