[Clas_gsim] Question on FFREAD cards

[Marco Ripani]

Hi everybody,
would you be able to tell me something about the following FFREAD cards 
for GSIM ?

NTARGET
CHAMBER
TARGET

For the EG4 ammonia target I have
NTARGET 3
CHAMBER 4
TARGET 'PROT'

In fact to avoid double counting on radiative effects that are 
calculated after extracting cross sections from the data, we decided to 
use the
NOGEOM 'PTG' 'FOIL'
and
NOMATE 'PTG' 'FOIL'
options. In this case perhaps it is unnecessary to specify NTARGET and 
TARGET ? What about chamber ?
I suppose it is still better to specify TGPOS although at the target 
position there may be practically nothing inserted in the GSIM description.
Could you please help me figuring out better the role of those 3 cards 
above and comment on the rest ?

Thanks a lot
Marco
