[Olympus] Talk for PANIC 2014

Hi Dmitry,
nice talk.

In the textboxes, I would recommend to make the paragraph left-aligned 
only, which avoids variable blank spaces and makes it more readable.

Check upper/case lower case consistency, e.g. slides 2,3

Slide 4
Not sure what you mean by 'geometry independent'. One disadvantage is:
"Density calculated from flow assuming conductance model"

Slide 6 %1 -> 1%
What do you mean by "Based on the same lepton-proton scattering" and why 
is that a disadvantage?
I would change this bullet to "Assumes TPE effect to be negligible"
Also, high momentum resolution is not really needed, so the 'poor' 
momentum resolution is not necessarily a disadvantage.

Slide 7: Type in y-label "Morm. counts"
Comment below the plots: Acceptance similar for opposite beam charge and 
toroid polarity combination

Slide 10:
What I would read from this plot:
Absolute luminosity agrees with SC lumi to within ~10%
Relative luminosities e+/e- agree within ~5%
Time dependent relative luminosities within 1-2%

Slide 11: What do we learn from observing ~1 or from observing a 
difference from 1 for the four-fold ratio?

Slide 12: Each crystals -> crystal

Are you going to show a rate or luminosity monitor for SYMB similar to 
slide 10, and/or also the ratio of 12 deg/SYMB?

Do you want to mention some of the work in progress / what are the biggest 
corrections to account for? (-> realistic MC etc.)

Best regards
   Michael
