Material budget in the Y2013 (X) geometry.  The top left plots number of radiation lengths encounted by a straight track at the given eta, phi.  The top right (bottom left) compares the ROOT and STARSIM geometries generated by AgML plotted vs phi (eta).  These are averaged over the other variable.  ROOT geometry in black, STARSIM in red.  The bottom right shows the difference in ROOT - STARSIM geometries vs phi and eta.  Less than 0.01 radiation lengths difference found integrated over the entire cave. 

Attached are material budget plots and differences for major subsystems.  Each PDF contains the material budget plots displaying number of radiation lengths averaged over all phi for the ROOT (left) and STARSIM (right) geometries created by AgML. The material difference plot is as described above.
