Using JP2 trigger luminosity values from Jamie's luminosity tracker, I've plotted the correction factors vs. instantaneous luminosity for scaler detectors during Run12 & Run13 500 GeV.

Instaneous Lumi := Integrated Lumi / Run Duration
Correction factor := Acc & Mul corrected scales / raw scales
There are 4 correction factors computed for each run, one for each spin state
