[Clas_hadron] Tsuneo's draft presentation for DNP meeting in Hawaii in Oct. (with a web link)

[burkert]

Hello Tsuneo,

Most of your slides look fine,  I have only a few comments/questions to 
some:

- slide 8: Eugine => Eugene

- slide 11: how is it possible that the distribution at phi=0 and 
phi=360deg do not match up?
    Shouldn't the rate at phi=0 and at phi=360 be the same? You seem to 
have a big step from
    0 events at 360deg to 7,000 events at 0 deg.

- slide 12: It would be better to make the selection cuts after all the 
corrections have been done.
    Your negative Mx^2 cut on the asymmetric distribution is not 
motivated. The asymmetric Mx^2 distribution
    comes mostly from 2 effects 1) events from the Al  wires, and 2) 
from the moving neutrons in
    deuteron (Fermi motion). If you were to correct for the moving 
neutron by using the completely
    measured final state, and then subtract the Al wires using the empty 
target measurement, you
    should get a nearly symmetric distribution around Mx^2 = 0, which 
would better motivate the
    cuts you apply. The final Mx^2 cuts  should come after slide #14 
instead of at the beginning of
    the analysis chain.

- slide 16: Perhaps it is only my Macbook screen, but this seems to be 
one of those examples how
    one can completely obscure the beautiful data quality in graphs that 
were cut and paste from
    some other files.  We should never show such poor quality graphs 
with our beautiful data.
    You can easily see the poor quality of the graph by magnifying it to 
300%.
