Hello Nathan,
The plots look reasonable. If you overlay an outline of the wafer dimensions on these
plots it will become clearer that the outer envelope of the hits is formed by the
overlap of the stereo and axial wafers. Since we require hit pairs in our current
track-finding those outside corners are clipped.

Subject: Re: Software Meeting, Thursday 9am/noon/6pm.
Following up on the kinematic gap in today's meeting, here are SVT x vs y hit positions
separated by layer (rows) and track charge (columns). This is still from the mock DSTs,
where I think only hits in tracks are available and there is a requirement of at least 5 hits
(layers?) per track. I also have the requirement of an Ecal cluster for each track in these
plots (which I'd guess is contributing to the box structure at small-y for negative tracks).
Maybe each gap in x is coming from a different layer (4,5,6), and the tracking projects
them giving the appearance of multiple gaps in one layer? That these gaps are not visible
in 1,2,3 (even if I zoom in and bin finer) could be due insufficient resolution in projecting
the gaps from 4-6, combined with 1-3 being single-sensor and having no gaps of their own?
Do the SVT experts think this all looks reasonable, and just a very accurate simulation:)?
Thanks,
Nathan

Here's one of the mock data DSTs where we see the things we discussed in today's
meeting. Like charge always zero for the 2-particle collections but sometimes ++ or
- for their daughters.

Dear HPS Software Group,
We will have our regular HPS Software meeting this Thursday, 9am Pacific, noon East Coast, 6pm Europe.
Sorry, I don't have much of an agenda. We will at least have the round table. If you would like to present something, please let me know.
Agenda:
* Software Roundtable -- All
* Questions? -- All
Please let me know if you would like to present something.
The connection will be with BlueJeans. Connection details at:
