  • Coincidence time spectrum with polarized 3He target
This cut should be valid for all 3He production runs starting from 3538( this is after re-timing BB).
Coincidence time cut: abs(DL.t3[0]-1035)<40 and also cut on !DL.edtpl T5 and no T3 (see plot below)

This cut should be valid for all 3He production runs from 3304 to 3323.
Coincidence time cut: abs(DL.t3[0]-765)<40 and also cut on !DL.edtpl T5 and no T3 (see plot below)

This cut should be valid for all 3He production runs from 3126 to 3203.
Coincidence time cut: abs(DL.t3[0]-865)<40 and also cut on !DL.edtpl T5 and no T3 (see plot below)
