shows that one can perfectly (fit/error>220) model the Compton photon rate with the cavity power and scintillator rate when things are running well at constant current.
cComptPhotonRateNorm= -220.4 + 0.278*cComptCavityPower + 5.183*cComptScintRateNorm
Perhaps cComptScintRate or cComptScintRateNorm should be added to the Qweak data stream.
