[Frost] Scale factor issue

[Park, Sungkyun]

To supplement your thinking about the scale factor of the multi-track events, I have made one more plot and attached with this email.
The attached plot is the scale factor per each center-mass-mass energy.
In the each energy, the x-axis is the π+ azimuthal angle in the rest fram of the π+ π- system 
we can check there are some structures on the angle.

If you want to know how I get the attached plot, go to the following web :

Michael, how do you make a sure that there are not any azimuthal dependence in the scale factor for the a single-track events.

Best Wishes

Hi,

After last weeks FROST meeting, I have given some thought to the azimuthal
dependence in scale factors. For a single-track events there should not be
any azimuthal dependence in the scale factors. However, for multi-track
events I think there can be azimuthal dependence in the scale factors. I
find it a bit tricky to think about.

I'm not sure what the best approach is for determining the scale factors
when an analysis requires multi-track events.

Sung and I have been communicating over email about scale factors and it
seemed like it would be good to hear from others as to how best deal with
scale factors when an analysis requires multi-tracks.

Take care,
Michael
