[BLAST_ANAWARE] vector asymmetry at NIKHEF

This question is to people who have the experience with GeN experiment
at NIKHEF. I'm pouring over Igor's thesis and notice that nowhere did
he mention that along with a vector asymmetry then have a tensor
asymmetry since Pzz = 1-3n0. In buiding his asymmetry he used formalism
similar to a hydrogen vector asymmetry, disregarding tensor piece (see
John C. message a while ago). Of course, the tensor piece in a
quasi-elastic channel will only contribute at large missing momentum (it
is identicaly zero at zero missing momentum). But at heigher missing
momentum its contribution can be upto 15% of the asymmetry. This this
accounted for.
