2. Outline Material Budget Plots Comparison and interpretation
Standard Geometry, Strawman A, Strawman B
Statistics for Strawman B
Geometry Debugging Tool
Hit level information
Comparison with MCTruth 2

3. Standard Geo x vs eta
Materials Subdetectors 3

4. Strawman A x vs eta
Materials Subdetectors 4

5. Standard B x vs eta
Materials Subdetectors 5

6. Subdetectors x vs eta
Standard Geo Strawman A Strawman B 6

7. Materials x vs eta
Standard Geo Strawman A Strawman B 7

8. Strawman B statistics
From ModuleInfo_StrawmanB.cc, Super Layer Sen Surf ~ 1.3 M cm^2, #pix ~ 178 M 8

9. Material Budget Plots More plots and info can be found here: 9

10. Geometry Debugging Tool
Goal
To examine low level info (e.g. hits, tracks, MCTruth) in order to validate geometry at a basic level (improvement on FastsimHitNtuplizer.cc)
Functionality
RecHits and all relevant info
SimHits and all relevant info (still in development)
MCTruth info (4-mom, pt, eta)
Reco Track info (kinematics, position, etc)
Sim Track info 10

11. Hit Ntuple Structure
Hits (sim and rec) are organized into trees (1 branch per tree)
Each branch has leaves containing relevant info (subdet, layer, position etc)
Root macros then select combinations of leaves for plots 11

12. Strawman B plots H-> 4l, 200 evts12

13. Strawman A plots 13

14. Strawman B MCTruth (muon gun)14

15. Strawman B MCTruth 15

16. Conclusion
Material Budget plots are available and reproducible (see twiki)
These will be updated as Strawmen geometry evolve
Geodebugger is almost ready
As soon as SimHit problem is fixed code will be committed to CVS 16
