Thanks for sending. Here are things I notice, which I'm sure you are well-aware of, but just in case. 


- I notice that the GEMs are off for the (e,e') study. Would it be possible to already start the (e,e'p) checkout of with the GEMs and LAD reference bar at the same time as the (e,e') elastics?

- Your overview plan goes from low-energy (e,e') to low energy (e,e'p) and then to GEM optics. Your detailed plan has GEM optics before LAD timing. I think GEM and LAD timing should happen before optics because it has the GEMs in the forward position, no?

- When we move the GEMs from forward angle to their final backward angle position, when will we do a survey? Same for after the SHMS move from 17 to 13.5.?

- What is the meaning of a prescale factor of -1?

Thanks,
Axel
