Question About TrackingManager 

Forum: Event and Track Management
Date: 19 Dec, 2002
From: lina <katia_lina@yahoo.fr>

Hi everyone,

I am trying to describe the properties of my detectors. It includes: - compton scattering and photoelectric effect on my first material. - scintillation production and all optical photon interactions on my second material .

So, my questions:

1- I don't understand exactly the mean of :
	const G4int NUMENTRIES 
  	G4double PP[NUMENTRIES]    
  	G4double SCINT[NUMENTRIES] 
  	G4double RIND[NUMENTRIES]  
  	G4double ABSL[NUMENTRIES] 
How can I know The number  NUMENTRIES ?
is it necessary to give a value of the reflection index and absolut 
lenght?

2- When I execute my program and using verbose 3, I can have informations I need them, like the position of the scattered photon when it hits the scintillator.

I have something like this:

*********************************************************************************************************

- My question, I do not want to have the informations of the e- and the
 optical photon. 
So, I did an instruction to delete these informations but I have always
 the sentence ( G4Track......Parent ID) and it takes a lot of places 
(specially for optical photon) and then my file is very full, 
so please, how can I delete them.
I tried to add an instruction in my own TrackingManager (the same 
G4TrackingManager), to put if it is gamma give these informations 
otherwise no, but I did not success.
Can you help me ?

Thanks in advance,

lina
