[Halld-offline] Tracking Software Meeting

[Elton Smith]

Hi Paul,

I agree with Nathan that some pid metrics should be added for kaons. But 
also for protons and pions, e.g. fractions of the time that 
pions/protons are correctly (incorrectly) selected.

It might also be useful to find metrics that help measure the program's 
ability to work in regions that are challenging. Some of that is 
identified in the "specific regions of physical phase space." I might 
add: interface between CDC and FDC (when parametrization changes); Very 
small angles close to the beamline are of special interest but also at 
the reconstruction boundary; stopping protons, e.g. kinematics that Beni 
is studying.

Cheers, Elton.

Please review the section on "Metrics" and propose additions/changes to the list of things we should monitor and the ranges of phase space we should study them.  Also, please add your name to the "Participants" list if I missed it.  Thanks!
