Computing the BHT3 cross section using the vernier scan technique with a single-gaussian model

 I've attached a document describing the details of the vernier scan analysis that produced the current BHT3 cross section value, 501nb.  Please have a look.

Rho reconstruction simulation study with FMS+FHC

    I studied the rho+ reconstruction with 10M pythia+GSTAR simulation events.

Unable to find agreement with prior values (again)

 The cross section for the BHT3 trigger is likely to change over time, both from beam-related backgrounds we can't identify and from changes in the gains of the individual towers which we can'

Trying to finalize the BHT3 xs

 I've written about the somewhat double-gaussian approach to fitting the BHT3 vernier scans already, so this is just a brief addendum:
