FLUKA: FLUSCW

[Laurent Aphecetche <aphecetc@in2p3.fr>]

Hi,

I defined a track-length binning (USRBIN) to score the fluence of
neutrons, and I'd like to use the fluscw to discard all neutrons but the
thermal ones. 
I made a few printout, but do not understand the energies I got
(typically PLA=-0.2528000E-10, which I would interpret as kinetic
energy=0.2528 eV, is that right?). How can I relate the PLA (in argument
list of FLUSCW) parameter with the low-energy neutron group ?

Thanks for your help,
