4) Optimal GSTAR+BFC settings for W-embedding, simulations
(aimed toward best achievable compatibility with pp500 data)
a) Pythia tune A for W-Pythia events. TBD for QCD-Pythia events
b) M-C W-event processed by GSTAR , output : .fzd
Setup options:
set field = "field=-5.0" # full reverse field"
set myGeom = y2009a
detp geom $myGeom $field hadr_on

c) Setting of 3 stages of BFC_mixer, 2 input sub-events (.daq , .fzd), 1 output event (muDst)
c1) processing of real sub-event, before mixing
