<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">Hi Maxime and Xinzhan,
<br>
I also had two suggestions / questions about slides 16 on position resolution <br>
<br>
1-) On the right plot, you have the fit giving a sigma = 72 microns resolution so why do you have below the statement that resolution < 74 microns?
<br>
<br>
2-) Maybe I am missing something but since you are extracting the resolution from the overlapping region and I guess you assumed that the two chamber have the same resolution, I would expect on the plot on the right being the distribution of the residual (x2_project
- x1) and with a width sigma_residual and them extract the resolution from this value by dividing by sqrt (2)
<br>
<br>
sigma_resolution = sigma_residual / sqrt 2, I don't understand how you directly plot the distribution hat gives you the resolution
<br>
<br>
Best <br>
<br>

<div>Hi Eugene,<br>
<br>
</div>
<div>0 is in the hole centre on GEM detectors. As you know we have a hole on each chamber to allow beam pipe to pass through. This plot uses GEM local coordinates. (origin is in the hole centre, x axis is in the horizontal direction, y axis is in the vertical
direction).<br>
</div>
<div><br>
</div>
The result is from the data taken during HyCal calibration run, during which we had 4 dedicated runs to test GEM efficiency, and we scanned 4 spots on GEM. These 4 spots are in the same height.<br>
<br>
</div>
The X axis is the coordinates (horizontal direction) of the spot, (in GEM frame), this plot shows efficiency in different GEM areas.
<br>
<br>
As during calibration, detectors are moving relative to beam, so I chose GEM local frame for this plot.<br>
<br>
</div>
<div>please let me know if you have comments on improving this plot.<br>
</div>

I am confused with slide 17 with GEM efficiency. Position with respect to what? What is 0 on X-axis?<br>
