How to produce track parameter resolutions (d_{0}, z_{0}, pt)

Efficiency of track reconstruction depends on the theta angle(angle between projection of momentum on z axis and momentum) and transverse momentum. You can see below dependence on theta for SiD_o1_v03 version of detector model. As you have noticed efficiency of reconstruction falls significantly after 40 due, to the problems with Forward Tracking Disks (after 120^{0} ) and Endcaps(both Tracker and Vertex) (< 40^{0} ).

  D0_resolution can be produced by running following script D0_resolution_angle.cxx:
