Pickle folder contains all data to plot figures, it can be opened with the following command:

import pickle
with open(directory + '***.pkl', 'rb') as fp:
    data = pickle.load(fp)
    print('----- Uploading of data file successfull -----')

In the pickle files, the interpolating functions of figures 11,13,15 are quadratic functions.
In the same figures, the model is the one presented in the corresponding section of the scientific paper: Figure 3 and 4.
