Hi,

At the bottom.of the run_card, you have the following parameter:
> #*********************************************************************
> # maximal pdg code for quark to be considered as a light jet *
> # (otherwise b cuts are applied) *
> #*********************************************************************
> 4 = maxjetflavor ! Maximum jet pdg code

If set on 5 then all "jet" cut will be applied on b quark (and in that case "bjet" cut are never use)
If set on 4 then all "bjet" cut will be applied on b quark and "jet" cut will be applied on the udsc quark
If set on 3 then all "bjet" cut will be applied on b/c quark and "jet" cut will be applied on the uds quark

Note that this parameter has a dynamical default. If you use a 4 flavor model then this parameter will be by default set to "4" but if you use a 5 flavor model then this parameter will be set to "5" by default.

Cheers,

Olivier
