Corrected Theoretical Transverse Asymmetry:
When I was doing the analysis, I realized, that there is a problem,
with the calculation of the mean transverse theoretical asymmetry
at high missing momenta. The last point, which has smallest statistics,
also has smallest error bar. Consequently it pulled down the neighboring
points with poorer statistics. This consequently caused a rapid drop
of the transverse asymmetry. In the new result I removed the last data
point.

Comparison of different theoretical models:
Simon provided me with various variants of the Golak's calculations.
We have PWIA, PWIAS and Full Faddeev calculations. I compared all
these models to our data. Here are the results:

Background Subtraction issue:
At one point I got worried, that the events form the random
background do not get subtracted properly from peak events.
I made some tests, and it seems, that things work fine:

MCEEP:
I started again trying to get MCEEP to work. I want to use it to
generate ntuples and analyze them with the same script as I am
using for my analysis. It took me a while to figure out how this
works. To get root tree one should not use the mceep_util command
(works only for plotting histograms). To generate root file
one should use command m2root. With newer version of ROOT and
Linux some modifications are required in order to get this script
compiled. However, the main thing is the Weight variable. In order to
get correct histograms, each variable has to be considered with a
weight corresponding to given event, when added to the histograms.
Now, that I get reasonable results, I can proceed and do some
simulations. However, there is still a long way in front of me.
Need to adjust acceptances, find proper model...
