--------- SST (Jonathan will give us an update)

— We need to finalize the full simulations with SST included. From Jason’s QA it looks fine, but we need to do the sim. with pile-up included so the final SST sim can be presented to DOE in October. 

— code not in CVS? What is the status on this?

— follow up with discussions with S&C (Jonathan)?

-- Alignment calibration is one pending item. I know Jonathan is working on this and he commented he would need help from Michael or Alex on the alignment codes. We may see the progress on this part.

-------- RUN15 calib.

- We discuss this at LBL. It would be good to run through responsibilities and timelines. What is missing to do this.

Notes: Sanshiro is making good progress on the PXL internal alignment. Should we expect a report probably next week?

— Embedding. With Mustafa preparing the QM probably less activity here until end of Sept. Also now there is an issue with the TPC simulator (an RT ticket is opened) which shows differences between ideal simulation and embedding in the projection residual. With this smearing, we probably won't see the impact of the HFTHitMover to the sensitivity level we will be looking to. Any other updates?

Comparison Sti/StiCA, RC and MC for pp510 with 10 MHz pile-up rate 
(simulation details)  http://www.usatlas.bnl.gov/~fisyak/star/MuMc/2013/

plots here:

The main conclusion is that:

  1. Efficiency of StiCA is 10-15% higher than Sti.

  2. No anomalies in momentum reconstruction is observed
