Hi, Chi!
I think I am able to write MC helicity and spin info to the CODA stream.
However, to make sure the same reconstruction classes can be used in the
same way for Chris' epel and DGen, I need to know which array element you
use for helicity and which for target spin orientation...
I am asking about the array POL(3) which is used by WRITECODAVERTEX()...
IS POL(1) used for beam polarization (with +/- indicating the helicity)
and POL(2) used for longitudinal target polarization (with +/- used for
spin orientation along the holding field)? Then POL(3) would be used for
transversal target polarization... but I do not need that for hydrogen.
Please tell me if that is the convention, or if you have a different one!
Thanks!
Adrian
PS: DGen will not be affected by these changes, the end result will be
that we will have helicity and target spin info when running Chris's epel
generator, like we have now for DGen.
