L10112120:29:42Looks like I still loose counts when closing the iris69050EG
just abaou 30% drop in count on the rayleigh channel6905
L10112120:40:23after optimizing convergence for both channels 68670EG
it looks like we loose about the same amount of counts
when closing the iris. This indicates perhaps the iris position
is not in the optimal spot.
