[b1_ana] TAC/iTAC resp.

[Elena Long]

Good evening,

It's using dAzz^{stat}(x_i) = 
SUM(drift(x_spec)*#ofContributedEvents(x_spec)) / Total#ofEvents(x_i)

Or, in easier-to-read LaTeX terms, see the first section in 
https://hallcweb.jlab.org/wiki/index.php/Elong-13-06-03#Including_Drift_by_Bin

Take care,
Ellie
