image</a> of the Lambertson that was logged had Hall A beam left of center. It may have been adjusted already and not logged. Hard to say if it's too far left of center since we can't see the wires anymore but might be worth taking a look. The comment was made
this morning regarding the Hall B beam so if you are looking I would line them up as best you can.</div>

I agree that the bunch compression is too large (>10 degrees from Eric's log) and we should not have to run like this for good transport. Definitely a topic for B-Team.</div>

Just some clarification about the Hall A energy discussion of this morning.</div>

<li>Hall A is requesting a certain energy error (dp/p) -1E-4. This is an abnormal request.</li><li>With FFB on in Energy mode, or when running Arc 2 it does as designed and brings the error even closer to zero down to the E-5 range. So not sure what this request is about, and I believe this abnormal request is the root of the Hall A issue. (Cipran ?) </li><li>This issue with monitoring the SLMs, is that we are running 0L04 so far off crest that the spots almost encompass the entire image frame:</li><ol style="list-style:lower-alpha">
