    keyword=run 4521: no problem, only small change in beam current

    The beam current changed a little during run 4521. Thus the observed changed in 
    detector counts (and double-peaking) is seen in "raw" (not beam-normalized) 
    detector.  Compare attachment 1 to the detector raw counts in the earlier log 
    entry.  Also, attachment 2 shows the (very clean) beam-normalized detector 
    signal.
    
    Unlike runs 4517-18, there isn't a problem here.
