<div dir="ltr">For Pengjia, <div> </div><div>a small list of things I would like to be check and try.</div><div><br></div><div>Try non linear fitting of calibration data maybe add polynomial term.</div><div>
If it is easier you could also try to do linear fitting on 4 points in each quadrants and we could have different sets of calibration constants depending on which quadrant the BPM are. Most likely we are in places where non linearities are significant ( maybe because of background noise with small signal )</div>
<div><br></div><div>Compare the calibration constants and pedestal values for different calibrations to see if we can see a pedestal dependence.</div><div><br></div><div>Look at the calibration for different pedestals to evaluate the dependence of position with pedestal.</div>
<div><br></div><div>Look at the spread of the beam current for production running.</div><div><br></div><div>Look at variation of calibration constants from 75 nA to 50 nA.</div><div><br></div>
<div>We might be able to do a linear interpolation of the calibration constants with current.</div><div><br></div><div>Other people can add their suggestions too.</div><div><br></div><div>Alexandre</div>
