helper module
Define functions to compute 1D longitudinal electric fields.
The ones used by Field will be in field_helpers.py from now
on.
- create_1d_field_func(field_values, corresponding_positions)[source]
Create the function to get spatial component of electric field.
- _evaluate_1d_field(pos, field_values, corresponding_positions)[source]
Interpolate an electric/magnetic 1D field file.
