[Sane-analysis] Abstract for the APS meeting.

[O. A. Rondon]

Hi Anusha,

Your abstract looks good. Since the talks are on different topics,
abstracts can be submitted by individual speakers. The only condition is
that the abstracts be first reviewed by the collaboration (represented
by the spokespersons and the analysis team), to keep the message from
SANE consistent and accurate, and to avoid duplications.

One suggestion on your abstract would be to change "independently
verify" to "verify by a different measurement technique, with
systematics uncorrelated to the original measurements". The point is to
emphasize that confirmation of the recoil polarization results by the
polarized target method is not just another independent measurement, but
a different method with its own systematics.

Cheers,

Oscar
