FWD Software

["Brandenburg, James" <jbrandenburg AT bnl.gov>]

Hi All,

 

I wanted to share some progress I’ve made since the end of the semester, as I had some time to really focus on the FWD system.

 

1. Several PRs are awaiting integration into StRoot (#636 https://github.com/star-bnl/star-sw/pull/636, #635 https://github.com/star-bnl/star-sw/pull/635, #571 https://github.com/star-bnl/star-sw/pull/571 )
2. One of the above PRs provides ability to run the code without a config file. I’ve thoroughly tested this now and it seems to work as expected.
3. I have finally learned a better way with git to keep the code organized so that I can make specific PRs but still keep a version of the code completely up-to-date
4. See the Wiki: https://github.com/jdbrice/fwd-software/wiki for info about how to checkout the `dev` branch and get updated codes (e.g. with the above PRs already included)
5. I’ve added scripts for running the most common simulation modes : “ideal” and “realistic” for either fst or ftt based tracking seeds. (See the `macros/sim` directory and the Wiki
6. I have developed a `StFwdFitQAMaker` to produce standard plots for diagnosing the fitting (when running on MC) – momentum resolution, charge mis-id rate, num hits per track etc. This should help since people can run this with their analysis and it will show if they are achieving comparable performance (as I expect) or not.
7. I have performed an initial J/psi analysis (MC only) and made a few modifications to the tracking with small improvements. I’d like to discuss this at the next meeting (Jan 5) so that we can move forward with a look at data and adding other info (FCS).
8. I’ve added a first set of PicoDst classes (StPicoFwdTrack and StPicoFcsCluster)
9. I want some FCS people to 1) Improve the Cluster class (I dropped some info that might be needed) and implement a similar StPicoFcsPoint Class (if that’s needed)
10. I have developed scripts to perform ‘standard’ productions of PicoDsts (From MuDst or StEvent) – I’ll work with Kaifeng and Ziyang to run this with the QA on the p+p 500 preview production so that we have a full dataset with FWD tracking.
11. I need some help with a few tasks listed on the Wiki, please take a look.
12. I’ve added directions for running the STAR code (including FWD) in docker container on your local laptop, in case others can benefit from that (See wiki)

 

Since we are still in the holiday season I do not plan for a meeting tomorrow (Next meeting on Jan 5^th). However, I am online tomorrow, so if people want to take a look at all of the new code etc. Kaifeng and Ziyang – if you are available we can discuss the next steps for the production.

 

I’m now very optimistic that we will have much more data to analyze soon. Looking forward to making progress in the new year with everyones help.

 

 

Best,

Daniel
