Subject: remarks to slides


Dear all,

I have a couple of small remarks to the slides which have been posted in
the last hours.

Fernando and Dan yours are final for me.

I gave my remarks to Elton and David in person.

Curtis, your slides have a lot of font problems in the powerpoint not so
in the pdf. But that makes it difficult to use the overlays here. I guess
it is a conflict with the new office we have here.
page 18: Is the diagram the correct one to the plots below.
page 23: I would really not show the plot for 1GeV, because the funny
         curve for 2007 is not caused by the geometry but by imperfections
         of the tracking at this time.
         In principle we should have run a simulation with the 2007 and
         2008 geometry and the current tracking code to have a fair
         comparison.
page 30: did you want to keep the sentence on vetoing charged particles in
         the FCal instead of mentioning the trigger application of the ToF

Eugene: slide 6, typo in simulation it is sumulation
        slide 10 typo in interaction is is interactoins
                 the picture of the geom is still the old 2007 one
        slide 11 are your systematic uncertainties agree with the ones
                 Simon send around, which are all the ones due to tracking
                 effects
        slide 14 is what you call a pion efficiency not a pion
                 misidentification
        slide 16 are your numbers for the BCal & FToF for the full
                 momentum range till 4 GeV. If yes i think it would be
                 good to quote for both detectors the efficiencies for the
                 momentum range we hope we can do PID, < 1GeV Bcal and
                 < 2.5GeV for the FToF
        slide 23 hm, it is maybe my bias from inclusive physics but i find
                 your first sub-bullet under 2 still la bit strong.

Tim: how are you doing with your final slides?

Cheers and thanks elke
