Subject: Re: Qweak working group - next meeting

Dear all,

I was supposed to report on inelastic/elastic separation for downstream 
collimator but I have  a meeting at the same time with our 
vice-president which I cannot avoid. Fortunately Juliette did the same 
thing (much more then I did) and put it in a fantastic clear 
presentation that there is nothing I could add to. The results she 
obtained agree with the ones I have so I would not repeat them here.

The only thing I would add is the way I decide on the size of the 
detector because sometimes it is confusing when we discuss the width of 
the detector. The distribution I use is Theta_out vs. Vertical position 
(shown in the attached figure). I require total acceptance of that 
kinematical shape. On the other two figures you can see the shape of the 
detector and the distribution of the inelastics. Juliette used exactly 
this detector size: 302-318 cm and length of 210 cm.

Once more I'll thank Juliette on here fantastic work.
