keyword=HALLA:p bad
Earlier today, around 18:10 I noticed that HALLA:p was not updating. A
related symptom is that HALLA:dpp was zero. After a call to MCC the
problem was quickly corrected.
This started after the CHL crash on Wednesday June 22.
Runs affected include 4838 through 4906.
run 4933 (before the problem) p=3654.53
runs 4938-4906 (during the problem) p=3654.59
run 4907 (after the problem was fixed) p=3654.52
Data analyzers beware, there's a possible 60-70 keV error if you use the
presumably incorrect 3654.59 value when generating missing mass for those
runs. It's not much but every little bit counts.
