ATLAS Tracking, Alignment and Silicon Detector Performance

Presentation for the Vertex 2010 conference. The presentation is supposed to cover pattern recognition and tracking performance, tracking efficiencies, spatial alignment strategies, V0 reconstruction, tracking related luminosity results, b-tagging, dE/dX results, material budget determinations with data. I cover most of these topics except for dE/dX results (given the presentation by Attilio Andreazza at the same conference) and tracking related luminosity results (due to time constraints).
