<div class="" style="word-wrap:break-word; line-break:after-white-space">Dear All,
<div class="">Following thee discussion we had on Friday about a possible shift of reconstructed momenta in the RG-A Fall18 outbending data, I checked the torus settings from the Mya archive. As you can see from the plot below, it seems that between 11/6/2018
and 11/12/2018, even if the torus current setpoint was -3770 A as usual, the MPS readback was -3800 and the hall probe read back was about-3796 A instead of the usual 3766. This is about 1% difference that would explain the missing mass shift observed by Geraint
in the 2pi channel and the sampling fraction shift observed by Cole.</div>
<div class="">From Mya, it seems everything went back to normal on 11/12 at 1pm. The runs affected by this potential shift are 5422 to 5476. </div>
<div class="">Best regards,</div>
