General notes:<br>
- Dark backgounds are dangerous in a presentation since they are prone<br>
to washing out text. White on dark can often be a problem, but the<br>
black (dark) text on the dark background is almost always a bad idea.<br>
It looks OK on a bright monitor, but that kind of thing tends to wash<br>
out and become unreadable on a projector. Be sure to test it on the<br>
machine you'll be using early next week so you have tiem to change the<br>
background if needed.<br></blockquote><div><br></div><div>I was a little worried about this as well, in particular with the light colored text on the light colored background. I think I am going to go back and use the style that my backup slides are in. </div>

- good set of backup slides<br>
<br>
<br>
Per-slide notes:<br>
p.5: should be: "... interacts with it through QED"<br>
similarly: "... interacts with the surrounding quarks ... through<br>
the color force."<br>
<br>
p.6<br>
- last bullet: "d2n is the average ..." (missing 'the')<br>
<br>
p.8<br>
- Title should be "Kinematic Coverage" (drop 'DIS', since it's a mix)<br>
- first bullet: "Data-sets at two beam energies: 4.7 GeV ..."<br>
- second bullet:<br>
- Make sure the x and Q^2 ranges are consistent with each<br>
other.<br>
- Note that the 5-pass data set was our 'primary' dataset (and<br>
is larger than the 4-pass data set)<br>
- I'd make a single plot showing both kinematic stripes. That will<br>
shows the combined kinematic coverage more clearly. Also note that<br>
the primary motivator for taking data at two beam energies was to<br>
set bounds on any Q^2 evolution of the points in the integrand.<br>
- white text on light colored, 'busy' background at the bottom<br>
(legiblility issue?)<br>
<br>
<br>
p.10<br>
- first bullet: "... allow us to evaluate d2 exclusively from our<br>
data" (as opposed to relying on world data extractions of 'R', etc)<br>
- grey text on light colored, 'busy' background at the bottom. I<br>
think it will be hard to read the bottom line, in particular.<br>
<br>
p.11<br>
- first 2 bullets: "Trajectory cut ..." instead of mirror cut<br>
<br>
<br>
p.13<br>
- diagram won't be clear to anyone unfamilar with the BB detector<br>
stack -- need to be able to explain diagram clearly and consisely,<br>
or rework the graphic to be simpler...<br>
- at minimum, I would crop out the black numbering on the right side<br>
and expand the size of the figure to make the labling legible<br>
<br>
p.14<br>
- since you're scaling all those histos to have equal area there is no<br>
information about how many good electrons are being lost along with<br>
the T2 cut.<br>
- I don't have a strong opion on changing this plot (since it is<br>
intended as a qualitative example), but you should be prepared to<br>
answer questions like the one above, if asked.<br>
- If you were to change the plot, I would suggest normalizing using<br>
the tail (ie. E_PSh > 400, or so) since those should (in<br>
principle) be minimally affected by any cut<br>
- Ideally, of course, you wouldn't normalize at all and just show<br>
"raw, +cut1, +cut2, +cut3" all on one plot so you can see the full<br>
effect. I realize that is tricky with the 'Rejected by T2'<br>
histo in particular though...<br>
<br>
p.15<br>
- Data _were_ taken ...<br>
- blue on blue won't be legible on the screen<br>
<br>
p.16<br>
- stick a 'Preliminary' on there somewhere, just so it's unambigous<br>
<br>
p.17<br>
-<br>
<br>
p.18<br>
- Slide title text changed color (grey instead of white)<br>
- add 'Error bars are stat. only' to note at bottom<br>
- might be nice to add a reference to Diana's thesis<br>
