Re: USRBIN Activity

Dear Andrew,

I bet you selected WHAT(1)>9 for the mesh choice in the USRBIN card. Look at
the manual, USRBIN card:

10.0 <= WHAT(1) <= 18.0: Quantities scored along a step, apportioned among
different bins according to the relevant step fraction.

Not Allowed:
- WHAT(2) = 219 (FISSIONS), 220 (HE-FISS), 221 (LE-FISS), 222 (NEU-BALA), 231
(X-MOMENT), 232 (Y-MOMENT), 233 (Z-MOMENT), 234 (ACTIVITY), 235 (ACTOMASS),
242 (NET-CHRG)

The nucleus production and decay is a discrete event that makes no sense
portioning along a (?) tracklength

Cheers

Francesco
