Subject: scraper setting 
After the orbit correction on the target straight section the scrapers work better.
One pair of scrapers works best:
GEEXDS2HA (outside straight section =  low Brho side) = -4.0 mm
GE02DS3HG (outside arc              = high Brho side) = -71.4 mm
All other scrapers are open (finished playing with scrapers ~18:20)
When one side is opened more one can cut more on the other.
We can attack the beam from both sides.
With scrapers good resolution, David already posts lifetimes of the isomer.
Details in paper log book.
