None Scintillation properties of BC 420

Hello geant4 users,
     I'm a really new user (I started 1 week ago) and I'm trying to 
implement the BC420 scintiiation properties in geant starting from the 
properties listed on the characteristics sheet provided by the factory. 
The question I have is very trivial maybe, but I couldn't find the 
The information I have are:
light output %anthracene
rise time
decay time
pulse width
wavelength of max emission
light attenuation length
bulk light attenuation length
and then I have two spectra: the wavelength vs the relative light output 
and particle's energy (p,d,t, alpha) vs the relative light output.

How do I get the scintillation yield? and the resolution scale?
Is the "FASTCOMPONENT" the light output as a function of the energy of 
the emitted photon?
The scintillator response to the different particles is, of course, 
different. I thought to use SetScintillationYieldFactor, but the 
responses are not simply proportional, their ratio depends on the 
particle energy.

Is there a documentation where all these properties are listed and well 
explained (I've already looked in the user manual)?

Thank you very much
Best regards
