Hello,
Chi's calculations are correct. The new library repeats the theta discrepancy from the v12 recrunch.
The discrepancy is on the order 0.34-0.44 degrees depending on the electron or proton. The newer
offsets were calculated using a Chi2 minimization in Q2 over the 4 variables pe, pp, te, tp and then
recalculated the four "proper" variables per event by the "Best" Q2. The offsets still showed discrete
jumps that corresponded to scintillator pads and so they are still 16 variable arrays by sector and
charge. I will have plots of before and after distributions coming out soon enough. I'm sending these
offsets out now before the plots of before and after for the sake of anyone using them for new analysis.
Offsets should be added as such
if (qwl==-1 && qwr==1) {
pe = pwl + PeLeft[ntl];
thetae = twl + TeLeft[ntl];
pp = pwr + PpRight[ntr];
thetap = twr + TpRight[ntr];
}
