Hello all, 

I'm using v1.6 to track particles through two bending magnets. I would like some more information on what particles are chosen for record in the X-trackOrbit.dat file.

i.e. the manual on pg 42 says ID0 is center (reference particle?), an ID1 is off center. So two questions: 

1. is ID1 the particle furthest from ID0?

2. My data is labeled ID1 and ID2 (no ID0). 

See attached file. Is ID1 the center in this case? 

Or is there a flag I need to set to get the center particle? 

Thanks,

Nicole
