Lot of 0 cluster in chamber 2 and 3, we need to tune the bending magnet and/or improve the veto to select a small spot.

this run is to see if the zero that we see is a trigger or magner problem: it seem that it's a trigger issue: now the fraction of zero seems similar to what we saw in the other physics runs.
