* `graph_file`: The path to the .csv file containing the graph of the response function.

* The file should be written in the following format: `x,y` (comma separated values), where x is the time and y the amplitude of the response function at that time point. Each pair of values should be written in a new line.

* `graph_time_unit`: Time unit in which the time on the response function graph is expressed. Should be a double.

* `graph_time_unit`: Time unit in which the time on the response function graph is expressed. Should be a double. Defaults to seconds (s).

* `graph_amplitude_unit`: The unit in which data on the y-axis of the response function graph is expressed. Should be a double. Defaults to volts per electron (V/e).
