To final results

1) Problem of the cross section model at x=A:

   - use 3He model = standard 3He inelastic and 3He F(y) then use M(3He)=3.2*NucleonMass in the step from F(y) to cross section

2) Cryo-target density:

   - Silviu is repeating his simulation for 4He at beam currents of 5, 10, 20, 40, 60, 80uA. He already performed the 95uA simulation. That will give us the shape of the extrapolation to zero beam current. We can then compare to our boiling data. 
   - compare to QE model to get the normalization factor (that is also relevant for the Calcium targets).

3) Al cross section (at forward angle, the long target is not an issue):

   - open the y_targ cut for dummy runs to include the dummy foils
   - can use also the dummy-4cm and dummy-10cm data

4) Acceptance cut effect

5) Systematics: take table from Nadia's thesis as a start.
