    Entry number 147225

    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.
