[Clas_gsim] want to use "bgrid_T67to33.fpk" for Torus map

[adhikari at jlab.org]

Could anyone give me the idea on how I could make GSIM use
"bgrid_T67to33.fpk" for the Torus field map rather than anything else?

When I look at the GSIM source files, I cannot find a single source file
that has 'bgrid_T67to33.fpk' written anywhere in it. It seems to me that
'bgrid_t.fpk' is used instead.

Can anyone tell me whether I can choose different field map options via
any ffread card or do I have to recompile GSIM after modifying one or two
source files?

Any insight would be greatly appreciated.
Thank you.
