[G14_run] From Dao Ho: DNP presentation

[A.M. Sandorfi]

Hi Dao,

A few remarks about the slides:
- As Volker Crede has already noted, slide 7 shows an approximate I^o
asymmetry. As you note at the bottom, this is one of Peng's slides and he
defines his "E*" elsewhere as being ~I^o. Maybe somewhere on the upper left
you can squeeze in " E* ~ I^0 ". Include an arrow to Peng's APS talk, maybe
in the lower right corner.
- the photos on slides 2 and 5 have been stretched and look distorted. CLAS
looks like an acorn in a vise. Adjust them to look more normal - it's OK if
they are a little smaller.
- in the lower-right plot of slide 9, put "(K Sigma)" above the "p+g" to
help the audience follow the point of the cut.
- on slide 11, you need some statement about future work to "tune the
Boosted Decision Tree"; the background (black) curves in the right panel
(upper and middle) of slide 9 do not really look that believable.
- replace the last bullet of slide 11 with something like
  " Study consistency between data subsets, comparing K0L asymmetries
    as well as pi-p and pi+pi- "
