Should the coefficients line 96 be added to the local dictionary before the expressions are evaluated for the preprocessor_settings? In the ARC implementation, tour_mode_choice_annotate_choosers_preprocessor.csv, references coefficients defined in the tour_mode_choice_coeffs and tour_mode_choice_coeffs_templates. They would only be available if the coefficients were added to the local_dict before the expressions are evaluated in line 88.
