scan_type
The integer parameter scan_type defines the type of wavenumber scan.
0 - current (kperp,kpar) to (swi,swf)
2 - current (kperp,kpar) to |k|=swf at constant theta
3 - current kperp to swf with constant kpar
4 - current kpar to swf with constant kperp
scan_type has to be defined for each wavenumber scan.
scan_type is part of the namelist &scan_input_.
