Issues

• run 6182 -- there is large beam excursion in this run, cut leave only about 400 patterns, just flag it as junk
• BMW coil6's amplitudes has been increased since run 6203
• the current of slug 130 is limited to 135 uA
• it looks like the energy slope is decreasing
• in slug 130, the yield of atl1 decreased by 1%
