Questions Regarding quark-gluon and gluon -gluon fusions

Dear Madgraph Team,

I have a question regarding the quark-gluon and gluon-gluon fusions .

I am trying to create the following processes separately.

The processes are :

p g > w- z j , w- > e- ve~ , z > e+ e-

p g > w- z j j , w- > e- ve~ , z > e+ e-

and

g g > w- z j j , w- > e- ve~ , z > e+ e-

I have the question regading the renormalization and factorization scales given in the default run_card.dat

**********************************************************************
# Renormalization and factorization scales *
#*********************************************************************
 F = fixed_ren_scale ! if .true. use fixed ren scale
 F = fixed_fac_scale ! if .true. use fixed fac scale
 91.1880 = scale ! fixed ren scale
 91.1880 = dsqrt_q2fact1 ! fixed fact scale for pdf1
 91.1880 = dsqrt_q2fact2 ! fixed fact scale for pdf2
 1 = scalefact ! scale factor for event-by-event scales
______________________________________________________________________________

For the above processes will the above values remain the same as given in the default run_card.dat ?

If not, then what should be the correct values for the parameters given above for the quark-gluon and gluon-gluon fusions ?

Thanks and Regards,

Arindam
