Summary
The ROOT tree variables filled in MollerAnalysis.hh in AddData , which is called from MollerAnalysis.cc.
The values are defined all over the place!
I am trying to catalog exactly where, and decide whether they should be defined differently...
- x, y, z
- x0, y0, z0
- kineE, px, py, pz
- kineE0, px0, py0, pz0, theta0
- kineE1, px1, py1, pz1, theta1
- kineE2, px2, py2, pz2, theta2
- kineE_org, theta_org
- type, volume, event, ev_num, hit, track
- ion, process, creator
- diffXS, totXS, rate
List of variables
O - used for this generator
X - not used for this generator (seems to always be 0 or -1)

Rate (Hz/μA), needs to be normalized to number thrown
|
track

Defined in tracking; value comes from hit information
|
Primaries are track = 1 (also 2, in case of mollers)

O
|
Defined in tracking GetEventID()

Currently the two moller tracks have the same event number

Notes
- For mollers, the number thrown is 2x the number specified; this will be changed in future versions...
- When secondaries are tracked, is second moller electron always track==2? Or are secondaries from first electron sometimes? Can we (should we) record secondaries from two moller electrons separately somehow?
