<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I attached an updated version of the plots I had made. These contain the same content as the previous email, but I cleaned up the graphs so it’s easier to compare each of the graphs to each other.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The calibration constants for the 16292-16297 run period seem to be relatively consistent with those from the 16700-16704 period, but I wanted to see what you all thought about it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I hope you all have a great week!<o:p></o:p></p>

<p class="MsoNormal">Hi Everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Apologies for the delay in getting these back to you; I made a time-costly mistake when I was trying to run the vertexing code on the skims.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I plotted each of the calibration constants as a function of run number on each of the attached slides. Some of them were for the 16292-16297 run period, and the others were for runs 16700-16704.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The fit parameters are defined as such: V = P_0 + P_1*ADC<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Where V is the reconstructed x or y vertex, ADC is the ADC signal from the raster, and P_0, P_1 are the fit raster calibration constants. I also included the current CCDB values as the green lines on the graphs. Please let me know if you
have any questions or what you think. The constants appeared to be consistent within each run period.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Sincerely,<o:p></o:p></p>
