Name: MaximumFlavour
Type: Integer parameter

Description:
The maximum flavour of the quarks in the process
Default value: 5
Minimum value: 1
Maximum value: 5

Name: CharmBottomMassOption
Type: Switch

Description:
Option for the treatment of bottom and lighter quark masses
Registered options:
0(ZeroMass)
The bottom is generated on mass shell, but zero mass is used in the matrix element
1(OnMassShell)
The bottom is produced on its mass shell, this mass used everywhere
Default value: 1

Type: Switch

Description:
Option for the treatment of the top quark mass
Registered options:
1(OnMassShell)
The top is produced on its mass shell
2(OffShell)
The top is generated off-shell using the mass and width generator.
Default value: 1
