We can cut out whatever data we want, but I think the Duality argument
(and prior experimental support) will serve us well for d2n and allow us
to use a lot of our resonance data.  It was always the plan to correct
d2_3He -> d2_n as a discrete object -- we have some (old) calculations
from Wally showing the correction is to d2n quite well determined this
way.  Needs to be updated though.
