It seems to me that the "Spill.targetPos" field in run schema is "8" (not "3") when spills were taken with the LH2-filled LD2 target. Is this a new feature of R006? If so, we don't need to exclude such spills manually by the spill quality assurance.

This is a newly-added feature of R006 according to Andrew. He has a script to make this change. Then this spill range is no longer regarded as bad by the spill quality assurance.
Actually I'm not sure how well we control the systematic uncertainty in ratio measurement. Since only the LH2 target was active in this spill range, the cancellation of systematic uncertainty between LH2 & LD2 doesn't work.
