Deadtime corrections

Radiative Corrections Worksheet

Overall corrections and Asymmetries

Run-by-run corrections:

electron efficiency: get A(HAMC with PID) - A(HAMC with 100% electron efficiency) run by run. Kai's PID input to Diancheng's HAMC
deadtime corrections: get 1/DT value run by run, both narrow and wide. Diancheng's HATS using HRS data as inputs
Pb: Compton result run by run, Diancheng <-- Note: this may end up with a single, overall correction.

Deadtime Correction Work Sheet:

This is a cross check of the deadtime correction. Can be done single-time for each kinematics/HRS (not run-by-run).
