Supporting Information for the article "Enhanced formation of interstellar complex organic molecules on carbon monoxide ice"

Chemical models ("Models.pkl") and structures (*.xyz files, figures 2 and 3) supporting the calculations presented in the article : "Enhanced formation of interstellar complex organic molecules on carbon monoxide ice"

The chemical models are stored as a dictionary of dictionaries with the following name per model:

e_XXXX_T_YYYY_CR_ZZZZ

where XXXX are the values of the epsilon parameter (see original article) sampled for \epsilon=0.5 and \epsilon=1.0 (additionally we release models with \epsilon=0.40, 0.45, 0.55, 0.60, 0.65, not discussed in the original article), YYYY is the dust temperature sampled within np.linspace(8,18, 26) and ZZZZ is the cosmic ray ionization rate, sampled within np.logspace(-18, -15, 22).

To open the chemical models, prepare a python script of the type:

++++
import pickle

def ice(dictionary, name, species): #Similar functions for gas molecules or surface molecules can be defined
    gas = dictionary[name][f"{species}"]
    surface = dictionary[name]["J"+f"{species}"+"(1)"]
    mantle =  dictionary[name]["K"+f"{species}"+"(1,1)"]
    return surface + mantle

Data = read_pkl_file('Models.pkl')
name = "e_1.00_T_10.0_CR_1.00e-17" #as an example
time = ice(Data, name, "Time")
CO= ice(Data, name, "CO") 

print(CO)
