  spoke with Arun on the phone, Arun pointed out that this is u!
 nacceptable to us, per Arun's suggestion, we did an NMR measurement to make sure our target is still good, see [ <a class="external free" href="https://logbooks.jlab.org/entry/4096938" rel="nofollow">https://logbooks.jlab.org/entry/4096938</a> ]. This issue has been discussed today in the 7:45 RC meeting and 8:00 MCC meeting, unfortunately the reason for this is not confirmed yet.
