The measured raw asymmetries are the physicl asymmetries
diluted by the beam polarization
, the target polarziation
, and
the dilution factor
due to the fact that we are using
He instead of
neutron target.:

Then the target asymmetry
can be extracted from the measured
asymmetries
and

Other variables are kinematics dependent, except
