DSLumi width has dropped about 100ppm since we started playing with the beam position late Wednesday. It was like someone turned a switch beginning with run 14249. I ruled out other IV's like backing out the C100's.
I first noticed this in the new N to Delta data, wondered if it were due to the lower QTOR field, and followed it back thru the hclog. But it's pretty dramatic in the QWAC plot of the DSLumi asymmetry

I've lost track of where we are in the game of musical beam positions, but the improvement has obviously persisted. What does it tell us about the lumi operation though?
