Tim: We would expect (due to observing this behavior in other detectors) that the real detector could get within 5-10% of expected momentum resolution. This 2016 detector certainly does not and that points to some problem.

MC Study? make sure that PC can actually help improve the momentum resolution within the context of alignment

Clean Selection: PC requires a very clean selection, don't have an upper momentum cut, remove positrons, make sure constrained tracks are building the distributions we expect

4 SVT Hit Recon & Calibration

Speaker: Rory O'Dwyer (SLAC)

5 Recon Needs News, Plans & Discussion

MattG's Notes From Discussion:

-- beam position/direction vs run
-- really need to understand cluster-track matching/track propagation to ECal
-- we need to have discussion about speed and size of reconstruction

Speakers: Norman Graf (SLAC National Accelerator Laboratory), Pierfrancesco Butti (SLAC)

6 MC News, Plans, & Discussion

MattG's Notes on Discussion:

-- momentum smearing in MC?
-- start looking at 3-prong: E/p, momentum resolution
-- generating MC at different beam/experimental conditions
---- target thickness, beam currents, SVT conditions

Speaker: Tongtong Cao (University of New Hampshire)
