<p class="MsoNormal">Maybe in analysis, can take into account amplitude matching a bit differently when it is close to saturation, do both coordinates saturate at the same time, or do you need to loosen the cut not loose those events or is is better to just
cut them off since unlikely to be a MIP ? </p>

<p><span style="font-size:9.5pt;font-family:"Trebuchet MS",sans-serif;color:#555555">I would not lower the HV on this GEM. The HV setting on this GEM was already pretty close to optimal from the efficiency scan. Some saturation in some small fraction of events
is inevitable. This plot does not indicate any problem. I do NOT think the gain is too high. In, fact, you see this in some fraction of events in EVERY module:
