QGSP_BERT_HP gave no data.

Hm, the liquid scintillator is created with the following:
LiqScin = new G4Material(name="LiqScin", density=0.86*g/cm3, ncomp=2); LiqScin->AddElement(C, natoms=1); LiqScin->AddElement(H, natoms=2);
It's then given various properties with
ScinPT = new G4MaterialPropertiesTable();
ScinPT->AddProperty( "RINDEX", pMom, rindex, numBins ); ScinPT->AddProperty( "ABSLENGTH", pMom, absorption, numBins ); ScinPT->AddProperty( "FASTCOMPONENT", pMom, ScintFast, numBins ); ScinPT->AddProperty( "SLOWCOMPONENT", pMom, ScintSlow, numBins );
ScinPT->AddConstProperty("SCINTILLATIONYIELD", effSY/MeV ); ScinPT->AddConstProperty("RESOLUTIONSCALE",1.0); ScinPT->AddConstProperty("FASTTIMECONSTANT", 1.*ns); ScinPT->AddConstProperty("SLOWTIMECONSTANT",10.*ns); ScinPT->AddConstProperty("YIELDRATIO",1.0);
Is there a missing property? The Detector Construction file is attached if more info is needed.
