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:

Best,
Maurik
