Sector 5 anomaly
I have previously reported seeing issues in padrows 38-40 of sector 5 in Run 8 data (see T0s in Run 8 and the second half of Run8pp zerobias charge asymmetry ).
T0s in Run 8
While studying residuals (generated from Sti, so-called "StiPulls") from Run 8 for work towards understanding h-/h+ issues, I decided to take a look at residuals in the time directio
J/psi Au+Au run 7 embedding - QA for sample in /star/institutions/lbl/andrewar/embedding/data/P08if/Jpsi_100
I run a quick QA for J/psi Au+Au run 7 embedding (sample in /star/institutions/lbl/andrewar/embedding/data/P08if/Jpsi_100/).

Au+Au run 7 embedding - QA for sample with fixed bug 1568 (A dip of pseudorapidity distribution in embedding outputs)
This is a QA for a pions sample produced when bug #1568 ("A dip of pseudorapidity distribution in embedding outputs") was fixed. There is however other issue.

Hadron shower transverse profile study for FHC
I study the pion+, pion-, neutron, anti-neutron with 60 GeV energy transverse profile in FHC. The particles are shot from (0, 0, 0) to the center of FHC.

Agenda:
1) Run10 Plan from S. Vigdor: doc, pdf files.
Our response:
Dear Steve,
Thank you for the draft run10 plan. We discussed your plan today, and would like to point out that it differs substantially from the PAC
recommendation. I think if it is indeed realized, we will not be able to complete the goals of RHIC beam energy scan program in a timelyfashion. At some energies, we are not scheduled to take data at all in Run 10 or 11. I am afraid that if your plan is implemented we will fail to demonstrate our seriousness about the BES to our collaborators, for many of whom this BES has renewed excitement about RHIC program.
In the attached table, we lay out an alternative plan, as STAR’s response to your proposal, for both 25- and 30-cryo week scenarios.
We believe that this alternative is more in keeping with the priorities laid out in the PAC recommendations. I would like to
emphasize that a week or so test with 7.7 GeV Au+Au collisions is crucial for the BES program. There are a number of questions about
machine performance, such as rates and collimation, and experimental performance, such as triggering, backgrounds, and vertex spot size, for
which this test is vital. This test must be done in order to plan for the long 7.7 GeV run in Run 11.
I hope that we will have a chance to discuss further before you make a final decision on this important run.

photon energy deposit compare using different vertex
I use two different vertexs to shoot photon with same energy through FMS and FHC, and study the differences between these two cases.
