[Clas12_verystrange] Xi reconstruction and field settings

[Michael Dugger]

Hi,

I will not be able to attend the meeting tomorrow.

I have a study of the single particle efficiencies and the reconstruction 
efficiency of Xi^- for each of the 4 field settings at

https://userweb.jlab.org/~dugger/vs/update8-15-2017.pdf

NOTE: I had problems using the official PID but, strangely, all else 
looked fairly good. I decided to push forward using a temporary PID scheme 
that seemed to be working OK. The slides regarding the single particle 
efficiencies is very similar to what I have shown before. Slides 13-15 
have the Xi^- reconstruction stuff.

Take care,
Michael
