Generators in "lips_case14_sandbox" environment

[jacubero]

You can see that there are 6 generators in the "lips_case14_sandbox" environment when you plot the network topology (for instance with the google colab "2_Datasets.ipynb"). However, in "prod_p" and "prod_v" you have 7 columns for each observation as there were 7 generators. Could you tell me if I am wrong? Which generator maps each column?
