Dave M. pointed out a potential issue with the diamond at 45/135 PERP. I believe that it is not problem for this experiment and definitely not solvable right now, but interesting topic to discuss in the future --> <a href="https://logbooks.jlab.org/entry/3952039" id="LPlnk123850">https://logbooks.jlab.org/entry/3952039</a></li><li style="font-size: 12pt; font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont;">
A friendly reminder to the Shift Worker to fill the spreadsheet with the data of the run --> <a href="https://docs.google.com/spreadsheets/d/19QWkjAPEiSd2scvAllYvgvB_puxKjFiSlh3z6EBfFck/edit?usp=sharing" id="LPNoLPOWALinkPreview">https://docs.google.com/spreadsheets/d/19QWkjAPEiSd2scvAllYvgvB_puxKjFiSlh3z6EBfFck/edit?usp=sharing</a></li><ul>

Perhaps you think it is a bit redundant since the RCDB is available, but it helps our students for fast cross checks of the runs.</li></ul>
