First pass on paper draft and analysis note

General comments (for detailed comments see the pdf files)

Paper draft:
- Very short at this time
- Experimental section needs to be expanded (including accelerator and polarization)
- Formalism should include vector definitions, otherwise the direction of angles is arbitrary
- No results for negative rapidities are shown in any of the detailed plots (but discussed in the text)
- Are any cuts on the invariant mass used in Fig. 1? (trying to compare the size of the asymmetries with the other figures by eye)
- Discussion of results should include more discussion of asymmetries and kinematic properties
- Variables in plots and text need to be consolidated
- Remove axis frame in panel 6 in Figs. 3 & 4

Analysis note:
- It is not clear what part of the analysis code should be copied and what is obsolete or output files
- The analysis code should be submitted to cvs (including instructions in a README file)
- For the purity determination, how useful/necessary is the pol3 fit (Fig 4.1 for example)
- In Fig 4.4 shouldn't the Kaon separation always be worse than that for protons? How do I understand the turnover at medium p?
- It looks like there is a large cos(2phi) modulation in the unpolarized distribution. Was any cos(phi)/phase or higher moment considered in the fitting procedure?
- How was the beam polarization included (mean polarization for the whole run or polarization weighted events)?
- I haven't gone through the trigger bias numbers in detail, but I think a fundamental assumption here is that the gluon contribution has no asymmetry and its effect therefore is a pure dilution of the amplitude. How do you get asymmetric systematic uncertainties from this? (Also, in the paper it looks -- by eye -- as if the asymmetry boxes are not consistent between the figures.)
