[d2n-analysis-talk] Hall A collab. talk rough draft

[posik at jlab.org]

Hi all,

   So I finished the rough draft of my talk for the upcoming jlab Hall A
collab. meeting. You can find it here:

      http://jlab.org/~posik/d2n/jlab_summer2011.pdf

 A couple of notes:

  *  Slide 8 with the kinematic coverage I may remove depending on what
Diana is showing.
  * Slide 11 I need to fix a typo in the BB Cer mirror cut plot it should
be "projected tracks on Cerenkov plane [m]"

  * Slide 13 shows the suppression of the pion peak due to the T2 trigger.
The plot I show is only for a hand full of runs, I am going to redo it
for more runs. I am also going to get a ratio of the prescale corrected
T1 and T6 events to the T2 events of the pre-shower energy from 0 to 200
MeV ie

        (ps1*T1 events + ps6*T6 events)/(ps2*T2 events)

To get an idea of how many pions in that peak are removed by using the T2.
Unless that does not seem necessary?

   * Slide 17/18 I have right now place holder plots in. I will be showing
Dave's prelim cross-sections at 4.7 and 5.9 GeV. These cross -section
plots will include
       - raw cross-section
       - N2 cross- section
       - positron cross-section
      -  (raw - N2 cross-section)

   * Slide 21 and on are just back up slides, mostly those that I showed
at the winter meeting this past December.


Let me know what you think.

  Thanks
Matt
