Hi all,
I finished the "white" generator in DGen. blastmc and TBLRaw are updated
to pass along cross section values.
when using the white channel(channel 2) in DGen, polarized cross section
on the spin state for the current event and the unpolarized cross section
will be passed to blastmc, written into coda file and read into
TBLRaw. they can be retrieved through TBLRaw::mc[0].MCxs and MCxs0.
crunching will book a branch in dst root file: dst:fMC. lr/flr ntuples
have two new entries: xs and xs0.
when filling histograms, use cross section as weight.
dst->Draw("MC.fTheta*57.3", "MC.fXs")
lr->Draw("tml", "xs*(xs>0&twl>0)")
Chi
