<div class="PlainText">Hi Silvia,<br>
<br>
We had some exchanges with Zhiwen. According to him the inclusive skim <br>
size is 40% of dst for the outbending runs, not sure where that 60% came.<br>
<br>
In case we drop the inclusive skim, decision should be made not just on <br>
the basis of the space, but also the time of the analysis, which will be <br>
obviously significant.<br>
<br>
In addition, in case we drop the inclusive skim, which was so far used <br>
in SIDIS, we will need e'hX skims, which will be only about a factor of <br>
1.5-2 smaller.<br>
<br>
Regards,<br>
<br>
Harut<br>
