Hello Daniel,

     I made the necessary changes. I had to restructure the way the trackprojections functions were working. Please take a look at the pull request with the changes and we can follow up more on github.

          Best,

Hi David,

 

It is used here to form track projections:

 

https://github.com/jdbrice/star-sw-1/blob/f0d1561ed96599264fed10593f39d200addf3a0d/StRoot/StFwdTrackMaker/StFwdTrackMaker.cxx#L1293

 

and the function for performing projections to a plane will probably need a new parameter to specify the angle (normal) of the plane here:

https://github.com/jdbrice/star-sw-1/blob/f0d1561ed96599264fed10593f39d200addf3a0d/StRoot/StFwdTrackMaker/include/Tracker/ObjExporter.h#L162

 

and the corresponding change needed in the “straight line projection function”:

https://github.com/jdbrice/star-sw-1/blob/f0d1561ed96599264fed10593f39d200addf3a0d/StRoot/StFwdTrackMaker/include/Tracker/ObjExporter.h#L136

 

Please let me know if you need more info

Hello Daniel, I can do this fairly quickly if you can point me to where in your tracking code you need this information for the projections. Once I make the changes I will submit a PR to your star-sw-1 dev branch. Best, David On Thu, Jan 9,

Hello FWD group, David K,

 

We have discussed many times the update needed for the position / angle of the FCS calorimeter projection planes. However, I’ve never been able to get the suggestions to work as expected (probably something simple that I am missing)

 

I’d like to ask for the FCS group to help me fix this. Specifically it doesn’t work in a simulation job (which I use as my closure tests for everything).

 

This can be provided in a number of ways (from most proffered to least but still acceptable)

• Submit a PR against my dev branch
• Push directly the changes as a commit
• Send me some working code updates to incorporate (point me to a directory with the changes etc.)
• We can meet and work through it together.

 

This is one of the things I want to check off for the upcoming production – so I’d like to take care of this ASAP and I suspect that with the right people it is a ~1 hr task.

 

P.S. sorry for the confusion with the meeting yesterday, we did have a short meeting with a few people.

We will have our next meeting on Jan 15^th at 11am

 

Best,

Daniel Brandenburg
