Xiaochao Zheng
discussed the status of the final analysis and PRL:
For the elastic
analysis, the left arm yield was 20% smaller than the right.
To solve the problem, Nilanga optimized
delta in the database, and Xiaochao
added 0.3 mm to the wall thickness
in order to get a good W spectrum.
For the N2
pressure curves, Xiaochao did not use the empty cell
runs, since they do not fit on the
curves. The pressure read from EPICS does
not appear to be the real pressure
inside the reference cell.
For the elastic
cross section results, the simulation agrees to about 5% with
the data. The simulation for
the elastic asymmetry agrees with the data to
within 1 sigma.
For the DIS
cross sections, the results agree with SAMC simulation at
the 10% level.
Xiaochao still
needs to finalize external radiative corrections and errors for
the target and beam polarizations.
Xiaochao presented
her draft on the PRL for A1n. For the A1n
plot,
the
collaboration suggested that the data
points for the experiment should
appear more obvious. The collaboration
also suggested that Xiaochao
should circulate a draft to the collaboration,
so they can give her feedback.
More work is needed for the theory
discussion part of the paper
