[Erd108] [EXTERNAL] Re: Additional simulation request

[Shyam Kumar]

Dear Kondo and Sourav,

Yes, I expect there will be further degradation in theta/phi resolutions if
you increase the material budget of the TOF layer (5% from 1%). I can check
the impact.
I feel that the tracklet idea is very interesting but I need to check in my
fast simulation, why it's performing well. I have some initial ideas based
on my experience but need to validate them producing a plot. For the
tracklet, I need to modify the Kalman algorithm then I can disentangle
again spatial resolution and multiple scattering contributions.

Thank you,
Shyam
