defines an homogenous electric field (not yet fully implemented)
See also MGNFIELD
WHAT(1) = largest angle (in degrees) that a particle is allowed to travel
in a single step
Default: 20 degrees
WHAT(2) = error of the boundary iteration (minimum accuracy accepted in
determining a boundary intersection)
Default: 0.01 cm
WHAT(3) = minimum step if the step is forced to be smaller due to a too
large angle
Default: 0.1 cm
WHAT(4) = Ex (x-component of the electric field, in kV/cm)
WHAT(5) = Ey (y-component of the electric field, in kV/cm)
WHAT(6) = Ez (z-component of the electric field, in kV/cm)
Note:
1) This option is being implemented, but it is not yet operational.
