newLT tagged plots are the same as previous plots applying new Ach and Alt.
2newLT tagged plots are using two times of Ach, i.e. A_measured = (A_raw - 2*A_ch - A_lt)/Pb/Pt.
(The name 2newLT can be misleading.)

Both asym_W2115.png and asym_W2325.png are run-by-run tracking of one W bin of 2115 MeV and 2325 MeV, respectively.
They have the same Ach as 2newLT's.
