Issues

• Since run 6099, the bcm asym is quite large (>~ 300 ppm) due to large asym in injector
• LQ2 quenched at about 3:25 am, making run 6105 through 6110 right arm only
• yield_atr1_mean of slug 125 is different from that in slug 124 (though the only difference between the two slugs is that we fixed the quenched LQ2), why change in left magnet will affect right at1?
• the same gap happens to yield of sams
